+title: 
+name: 🪳 Bug report
+about: Report a defect. Do not use this for support requests and feature suggestions.
+---
+
+Please explain
+    (1) what behavior you expected
+    (2) what behavior you observed
+    (3) and how we can reproduce the issue.
+
+You don't have to quote the above lines to do that.
+
+Please include a backtrace in your report.  In most cases doing:
+
+    M-x toggle-debug-on-error RET
+
+and then going through the steps again should result in a backtrace.
+
+Also post the output of:
+
+    M-x magit-version RET
+
+Before reporting a defect please try to reproduce it using an Emacs instance in which only Magit and its dependencies have been loaded. Other packages or your configuration should not be loaded. This makes it easier to determine whether the issue lays with Magit or something else.
+

+# -*- mode: org -*-
+* v0.8.6    2025-03-15
+
+Bug fixes:
+
+- ~transient-show-summary~ errored for commands that have neither a
+  summary nor a docstring.  0886651d
+
+- ~transient-format-description~ errored for ~transient-information~
+  and ~transient-information*~ suffixes.  #366
+
+- ~transient--wrap-command~ failed to load autoloaded commands.
+  40308623
+
+- ~transient-suffix-object~ errored if a command is bound more than
+  once and is invoked using the mouse or ~RET~.  f69e1286
+
+- For some releases ~transient-suffix-object~ errored if it could not
+  identify a unique suffix, which helped establish that it is in fact
+  legitimate to use this function as a predicate.  No longer error if
+  there are zero matches, but continue to error if their are multiple
+  matches that cannot be disambiguated.  4a06aeb0
+
+* v0.8.5    2025-03-01
+
+- Added new faces ~transient-key-recurse~ and ~transient-key-stack~.
+  58e22554
+
+Bug fixes:
+
+- ~transient--setup-recursion~ did not consider the ~resurse~ shorthand.
+  32a7e256
+
+- The parent group was not always stored in suffix objects.  #354
+
+- Invoking a suffix of a sub-prefix (which is configured to return to
+  the outer prefix), did exit instead of returning, if the suffix's
+  own behavior was not explicitly specified.  #352
+
+- The color of a suffix that returns to the outer prefix, was wrong
+  when there isn't actually an outer prefix.  e88005d2
+
+- When potentially removing other bindings for the same command
+  while adding a new binding, false-negative avoidance was too heavily
+  favored over false-positive avoidance.  #355
+
+- Defining the ~transient-higher-level~ face involves calling
+  ~face-attributes~ on another face.  That call requested the value
+  for the current frame (which may not exist yet) instead of using
+  the default.  #359
+
+- When the transient window is hidden while the minibuffer is used,
+  then it was not restored if using Helm.  #361
+
+- Non-suffix command that aren't accessed via a symbol, were not
+  properly wrapped to ensure post-command cleanup happens even in
+  case of an error or if the user aborts a minibuffer use, causing
+  the menu window to get stuck.  08201f06
+
+* v0.8.4    2025-02-01
+
+- Added new option ~transient-show-docstring-format~.  65cd6cec
+
+- Unless called with a prefix argument, ~transient-toggle-docstrings~
+  now only shows docstrings for the current menu invocation.  13f3f5e0
+
+- The ~##~ macro from the ~llama~ package can now be used after keywords
+  in group specifications (including suffix bindings).  7c650436
+
+- Suffix commands can now be advised using the new ~advice~ and ~advice*~
+  slots available for suffixes and groups.  This feature is still
+  experimental.  #340
+
+- ~transient-scope~ can now also match against prefix classes, not just
+  specific prefix commands.  #334
+
+- The default level of a suffix command can now be set via its
+  prototype, using the new function ~transient-set-default-level~.
+  f6c249c7
+
+* v0.8.3    2025-01-03
+
+- Added new constant ~transient-version~.  3022f6d5
+
+* v0.8.2    2025-01-01
+
+- Added support for displaying the transient menu in a dedicated
+  frame.  bf58c0bb
+
+- When including a group via a variable, the imported value can now be
+  a top-level group.  eebcbe30
+
+- The transient window is now fitted to its buffer horizontally as well.
+  fd9811ea
+
+- Added new command ~transient-copy-menu-text~.  042f37aa
+
+- Added new command ~transient-toggle-docstrings~.  52679f98
+
+- Added new command ~transient-describe~, which can be bound as many times
+  as needed to show help for arbitrary things.  5a18a791
+
+Bug fixes:
+
+- The use of ~display-buffer-full-frame~ was prevented too aggressively.
+  5353464b
+
+- Fixed remembering and restoring the old value of the ~no-other-window~
+  window parameter.  de984302
+
+- When a command is bound multiple times and the instances use different
+  transient behavior, then the behavior (and color) for the last binding
+  was used for all bindings.  fe71a7e7, a99dcda9
+
+- Enabling ~transient-force-single-column~ resulted in an error.
+  28347e59
+
+- ~transient-toggle-common~ used to exit the menu.  98c01b84
+
+* v0.8.1    2024-12-08
+
+Bug fixes:
+
+- Interactively setting the level of a transient prefix resulted in
+  an error.  #337.
+
+* v0.8.0    2024-12-06
+
+- While the minibuffer is in use, the menu window is now hidden by
+  default.  The new option ~transient-show-during-minibuffer-read~ not
+  only controls whether the menu stays visible while the minibuffer
+  is in use, but also whether it may be resized if necessary.  This
+  new option replaces ~transient-hide-during-minibuffer-read~.  #330
+
+- When returning to a prefix whose ~refresh-suffixes~ slot is non-nil,
+  its suffixes are now re-initialized.  #327
+
+- Added documentation for ~inapt-if*~ slots to manual.  179545a6
+
+- ~transient-args~ now takes a prefix command or a list of prefix
+  commands as argument.
+
+- ~transient-scope~ now takes a prefix command or a list of prefix
+  commands and/or a prefix class or list of prefix classes as
+  arguments.  It can still be called without any argument, but that
+  should only be done in functions that take part in setting up a
+  menu, not in a suffix command.
+
+- Added new generic function ~transient-prefix-value~, giving finer
+  control over how the value returned by ~transient-args~ is determined.
+
+- Added support for implementing ~transient-init-scope~ methods for
+  prefix classes.
+
+- ~transient-setup-buffer-hook~ is now run later to allow overriding
+  more default settings.
+
+- The new prefix slots ~display-action~ and ~mode-line-format~, can be
+  used to override ~transient-display-buffer-action~ and
+  ~transient-mode-line-format~ for individual prefix menus.  #332
+
+- Updated the manual considerably.
+
+Bug fixes:
+
+- Fixes some menu navigation edge-cases.
+
+* v0.7.9    2024-11-04
+
+Bug fixes:
+
+- Fixed a recent regression in ~transient-suffix-object~.  #325
+
+- The height of the transient window was fixed even it used the full
+  frame height.  5478d4e6
+
+* v0.7.8    2024-11-02
+
+- Additional potential mistakes in menu definitions are now detected.
+  bbda5bb6, 8873c300
+
+- Added new (and still experimental) ~environment~ prefix slot, which
+  can be used to, for example, implement a cache to be used while
+  refreshing the menu.  05c011b8
+
+- When navigating through the menu using the keyboard or hovering a
+  suffix command with the mouse, information about the command is now
+  shown in the echo area or using a tooltip.  #282
+
+Bug fixes:
+
+- When the command that exits a transient uses the minibuffer,
+  ~transient-current-*~ variables were not immediately reset to
+  ~nil~. #323
+
+- Key sequences with three or more events broke
+  ~transient-suffix-object~.  #324
+
+* v0.7.7    2024-10-04
+
+Bug fix:
+
+- Fix a regression introduced by the previous commit, which broke
+  dynamic prefixes that use a ~:setup-children~ function to prepare
+  their suffixes.  #313
+
+* v0.7.6    2024-10-01
+
+- ~transient-active-prefix~ now accepts a single prefix symbol, in place
+  of a list of such symbols.  #307
+
+- ~other-frame-prefix~ and ~other-window-prefix~ can now be used while a
+  transient prefix is active.  #305
+
+- Added new macro ~transient-with-help-window~ for use in ~:show-help~
+  functions.  #309
+
+* v0.7.5    2024-09-01
+
+- Updated tooling.
+
+Bug fixes:
+
+- ~static-if~ is now used correctly.  0e35673e
+
+- When an existing window ends up being used to display the transient
+  buffer, then the previous value of the ~no-other-window~ parameter is
+  now restored, when the transient is exited.  #302
+
+- The names assigned to suffixes, which are defined using lambdas in
+  the prefix definition, are now guaranteed to be unique.  #304
+
+* v0.7.4    2024-08-05
+
+- Added new function ~transient-active-prefix~.
+
+* v0.7.3    2024-07-13
+
+- Refactored code responsible for inserting columns.
+
+Bug fix:
+
+- The ~transient-current-*~ variables are intended to only be used by
+  suffix commands, when they are invoked from a prefix.  Previously
+  they were only cleared when the prefix is ultimately exited, which
+  meant that they unintentionally were accessible in timers.  Now the
+  values of these variables are nil when used outside their intended
+  scope.  0e0ece32, f2cb28a5
+
+* v0.7.2    2024-06-24
+
+- Added support for adding suffixes that activate value presets.  #183
+
+Bug fix:
+
+- Restored the ability to individually set infix arguments if the
+  prefix's ~refresh-suffixes~ slot is non-nil.  8db5f0fd
+
+* v0.7.1    2024-06-19
+
+- Added a workaround for ~emoji.el~ from Emacs 29.1 calling an internal
+  function using an outdated number of arguments.  #288
+
+* v0.7.0    2024-06-18
+
+- Added new macro ~transient-augment-suffix~, which can be used to
+  specify the suffix behavior of a command that was previously defined
+  as a prefix, using ~transient-define-prefix~.  2fd3ea14
+
+- Added new function ~transient-scope~, which is just a convenient way
+  to get the value of the ~scope~ slot of the ~transient-prefix-object~.
+  7f6c39c5
+
+- Added new hook ~transient-setup-buffer-hook~, which is run early when
+  setting the transient menu buffer.  #283
+
+- Added new class ~transient-information*~, a variant of recently added
+  ~transient-information~ class.  8a80e952
+
+- By default our macros that define commands, mark those as for
+  interactive use only.  ~(declare (interactive-only nil))~ can now be
+  used to overwrite that.  fcc60e27
+
+- Groups now also accept ~:inapt*~ predicates.  3d395d64
+
+- Spaces between columns is reduced from three to two.  dd93001e
+
+- Removed unused ~transient-plist-to-alist~ function.  1251faf0
+
+Bug fixes:
+
+- ~transient--force-fixed-pitch~ was run to late to always succeed.  #283
+
+- Key binding conflict detection was too strict, taking hypothetical
+  bindings for inapt commands into account.  c356d1bc
+
+- Key binding conflict detection did not consider bindings in regular
+  keymaps, such as ~transient-base-map~.  2698d62d
+
+- ~func-arity~ gets confused when a function is advised, so we had to
+  add a wrapper function ~transient--func-arity~.  91dd7bb3
+
+- Some mistakes, that can be expected to occur when defining suffix and
+  prefix commands, were not detected.  7e827c31
+
+* v0.6.0    2024-03-21
+
+- On Emacs 28.1 and later, all infix commands and suffix commands
+  that are defined inline (i.e., using a lambda when defining a prefix
+  command), are now hidden from ~execute-extended-command~ (aka ~M-x~) /by
+  default/.  It was already possible to hide these commands, but users
+  had to opt-in explicitly.  After refactoring how these commands are
+  declared to be unsuitable for ~M-x~, it is now possible to hide them
+  /without/ also hiding other, unrelated kinds of unsuitable commands.
+
+  I recommend that you instruct ~M-x~ to hide /all/ unsuitable command.
+  This requires that you customizing ~read-extended-command-predicate~,
+  because the Emacs authors have decided that this should be an opt-in
+  feature.
+
+  Note that this has no effect on Emacs releases before 28.1.
+
+- Added documentation stating that ~:class~ has to be specified when
+  using ~:setup-children~.  beecdc85
+
+- Added a new prefix slot ~column-widths~, which can be used to specify
+  the minimal width of each column in all ~transient-columns~ groups of
+  that prefix.  92e8952e
+
+- When assigning a name to a suffix that is defined inline, we no
+  longer use the suffix description, iff that would result in an
+  overly long name.  81a108ba
+
+- Functions used as the value of face slots can now take one
+  argument, the suffix object.  Functions that take zero arguments
+  are still supported.  Additionally, ~transient--pending-suffix~ is
+  bound around calls to these functions, but it is better to pass
+  the object as an argument.  f582a9bc
+
+- The new ~definition~ suffix slot can be used to specify a default
+  function definition that is used if no function body is provided
+  using ~transient-define-suffix~.  5b334a51
+
+- Taught ~transient-suffix-object~ about ~transient--pending-suffix~.
+  20a3770d
+
+Bug fixes:
+
+- If ~transient-parse-suffix~ and ~transient-parse-suffixes~ are called
+  with an invalid value for their ~prefix~ argument, they failed to
+  detect that.  03e752d9
+
+- If ~nil~ is encountered inside a group specification, that was
+  silently ignored.  Now an error is signaled.  8c01a1eb
+
+- ~find-function~ wasn't able to locate the definitions of infix
+  commands anymore.  a30df67b
+
+- There was no binding for ~ignore-preserving-kill-region~ in
+  ~transient-predicate-map~.  0fc87002
+
+- Invoking a non-symbolic non-suffix command, caused an error.
+  bd2a5ea0
+
+- When a group begins with an included subgroup, that affected what
+  group class was assumed, in the absence of an explicit specification.
+  df36bc87
+
+- ~transient--suspend-override~ failed to move out of the minibuffer
+  before refreshing the transient buffer.  833143ba
+
+- When a suffix command signaled an error during a trivial phase
+  (which does not involve, e.g., the minibuffer), then the transient
+  window was not deleted when the debugger was entered.  9d8f361f
+
+- When a prefix was refreshed, the wrong color was used for suffix
+  commands that exit the prefix, indicating that would cause a return
+  to the outer prefix, even though there is none.  f51c144a
+
+- Calling ~transient-infix-read~ with an invalid value, resulted in
+  a confusing error.  Now an appropriate error is used.  3ebb6acf
+
+- When third-party code or user customization managed to display
+  another buffer in our dedicated window, then that buffer got
+  killed when we tried to kill the transient buffer.  #271
+
+* v0.5.3    2023-12-16
+
+- Fixed regression when setting ~:pad-keys~ for a ~transient-columns~
+  group.  #269
+
+* v0.5.2    2023-12-05
+
+- Fixed formatting issues in the manual.
+
+* v0.5.1    2023-12-05
+
+- Added a new introduction by JD Smith (@jdtsmith).
+
+Bug fixes:
+
+- Faces that use a box are now defined more defensively to protect
+  against unexpected values and provide reasonable fallback colors.
+  413310cd, b8aefce3
+
+- Only prepare to return to the parent transient if there actually is
+  a parent.  The only negative effect of failing to do this was that
+  the suffix was colored wrong, since ~transient--do-return~ falls back
+  to behave like ~transient--do-exit~.  5f2cfc9f
+
+* v0.5.0    2023-11-28
+
+- Some suffix commands exit the transient from which they were
+  invoked, while others don't (allowing the user to invoke another
+  suffix without first having to enter the transient again).
+
+  Until now it wasn't possible to tell which category any given suffix
+  falls into, at least not by default.  Now the key binding of each
+  suffix is colorized to indicate its transient behavior.  Red means
+  that the suffix exits the transient, and blue means that it does
+  not.  Keys for suffixes that currently cannot be invoked are gray.
+
+  Likewise, the thin line, that is drawn between the transient popup
+  buffer and the minibuffer, is used to indicate what happens, if you
+  invoke a command that is not a suffix.  Most prefixes do not allow
+  non-suffixes to be invoked, so this line usually is gray.  c8a9ac51
+
+- Many faces have also been improved.  This involves changing which
+  built-in faces they inherit from, some explicit changes to their
+  appearance, and semantic clarifications.  Of course your mileage may
+  vary — it's possible that some face just happened to look right with
+  your chosen theme, but now it has to be themed to achieve that
+  again.  47d3f01d 71d16d86 et al.
+
+- Added a new face, ~transient-delimiter~, which is used for parentheses
+  around values and the pipe character used to separate possible values
+  from each other.  567b5d54
+
+- Added a new command ~transient-toggle-level-limit~, bound to ~C-x a~,
+  which temporarily shows all suffix commands a transient has to
+  offer.  This makes it possible to occasionally use more obscure
+  commands and arguments, without having to always display them.
+  For more information see [[https://magit.vc/manual/transient/Enabling-and-Disabling-Suffixes.html][Enabling and Disabling Suffixes]].  #243
+
+The changes described below, only directly affect package authors and
+users who implement their own transients.  If that does not describe
+you, then all you have to know is that many features were fine-tuned
+and otherwise improved, opening up some new use-cases and making some
+things easier to implement.  This will hopefully lead to improvements
+in your favorite transient-using packages in the coming months.
+
+- It sometimes makes sense to bind multiple keys to the same suffix
+  command, e.g., because they behave differently based on the suffix
+  description, or some other slot that can be set per binding.
+  Previously these bindings shared a visibility level; how this can
+  be set individually.  #153
+
+- While functions are run, which format strings to be inserted into the
+  transient buffer or to determine whether other aspects of a suffix,
+  that transient buffer no longer is the current buffer.  Instead the
+  buffer in which the prefix and its suffixes operate, is the current
+  buffer.  This affects functions such as ~transient-format-description~
+  and those found in predicate slots such as ~if~.  In contexts where
+  the transient buffer is needed but the other buffer happens to be
+  current, the new macro ~transient-with-shadowed-buffer~ can be used
+  to temporarily change that.
+
+- The new suffix slots ~face~ and ~inapt-face~ can be used to specify how
+  a suffix looks, which in simple cases is more convenient than using
+  a function as ~description~ and adding the face there.  The values of
+  these slots should be faces or functions that returns a face.  The
+  default for ~inapt-face~ is ~transient-inapt-suffix~, but in some cases
+  it is undesirable to apply this face to the whole description, so
+  this can be overridden by setting this slot to ~nil~ for individual
+  suffixes.  The default for ~face~ is ~nil~.  c2a75880 8e15a29b 71399d21
+
+- Added new variables ~transient--pending-suffix~ and
+  ~transient--pending-group~, which are bound while a suffix/group is
+  being inserted.  These are mostly intended for internal purposes,
+  but in some rare complex cases package authors might need them too.
+  0717589a 70e8dc80
+
+- Sometimes it is useful to display some information in the transient
+  buffer, which is not associated with a suffix command.  The new
+  class ~transient-information~ can be used for that purpose.  Children
+  that use this class are very similar to regular suffixes, the lack
+  of a command binding being nearly the only difference.  #226
+
+- Instead of a list of choices, the value of a suffix's ~choices~ slot
+  can now be a function that returns such a list.  #212
+
+- Per-suffix functions that format its description (specified using the
+  ~description~ slot) can now optionally take one instead of zero argument,
+  the respective suffix object.  09be367b
+
+- Added a new command ~transient-echo-arguments~ intended for use in
+  examples and bug reports, when a prefix must bind some command, but it
+  does not really matter which.  Using this command is less verbose than
+  having to implement a dummy every time, and it comes with some goodies.
+  I.e., it reports information about the prefix from which it was invoked.
+  faa3d09d
+
+- When a command was defined using ~transient-define-suffix~ and an alias
+  for that command was created using ~defalias~, then the alias had no
+  access to the associated suffix object.  Now it does, which makes it
+  possible to bind the same command multiple times in a prefix, and make
+  it behave differently depending on the symbol-name that was used to
+  invoke it.  f43aee1a
+
+- The values of a prefix's ~transient-suffix~ and ~transient-non-suffix~
+  slots should now be a boolean.  The value of the ~transient-suffix~
+  slot has to be handled differently for different types of suffixes.
+  I.e., infix arguments must ignore it, and sub-prefixes must honor
+  it but to do so they must use a different pre-command.  Previously
+  booleans were not supported and the previously recommended values,
+  ~transient--do-stay~ and ~transient--do-exit~ are still supported (but
+  they are "corrected" for sub-prefixes).  For the ~transient~ slot the
+  use of booleans was always allowed and recommended.  8098d175
+
+- For sub-prefixes a value of ~t~ for the ~transient-suffix~ slot of the
+  parent prefix now means that suffixes, which exit the sub-prefix,
+  return to the parent prefix, instead of exiting that as well.
+  784887b7 5ad5b627
+
+- In addition to booleans and pre-commands, the values of the
+  ~transient-suffix~, ~transient-non-suffix~ and ~transient~ slots
+  may now also be pre-command "shorthands", e.g., use ~leave~ instead
+  of ~transient--do-leave~ (which in some cases is a good value for
+  `transient-non-suffix`). 9617b6c7
+
+- ~transient--do-replace~ now behaves as documented and implied by its
+  name.  Use the new ~transient--do-stack~ if you want to return to the
+  outer prefix.  94661e0c
+
+- Added a new prefix slot ~transient-switch-frame~, which allows
+  specifying the transient behavior of ~switch-frame~ per prefix and
+  independently of the transient behavior of other non-suffixes
+  (specified using the ~transient-non-suffix~ slot).  609dabfd
+
+- Added a new function ~transient-prefix-object~ to allow package
+  authors to avoid the following unfortunate complication.
+
+  While a transient is being setup or refreshed (which involves
+  preparing its suffixes) the variable ~transient--prefix~ can be
+  used to access the prefix object.  Thus this is what has to be
+  used in suffix methods such as ~transient-format-description~,
+  and in object-specific functions that are stored in suffix slots
+  such as ~description~.  When a suffix command is invoked (i.e.,
+  in its ~interactive~ form and function body) then the variable
+  ~transient-current-prefix~ has to be used instead.
+
+  Two distinct variables are needed, because any prefix may itself
+  be used as a suffix of another prefix, and such sub-prefixes have
+  to be able to tell themselves apart from the prefix they were
+  invoked from.  Regular suffix commands, which are not prefixes, do
+  not have to concern themselves with this distinction, so they can
+  use this function instead.  In the context of a plain suffix, it
+  always returns the value of the appropriate variable.
+  37307c1b
+
+Bug fixes:
+
+- cc0fa805 transient--post-command: Redisplay after universal argument
+- dd970cd4 Compile suffix commands that are defined inside prefix definitions
+- b150b48b transient-quit-one: Cancel prefix-arg instead of exiting transient
+- 7c08beb8 Revert "transient-{set,save,reset}: Stay transient"
+- f8209cc8 transient--maybe-pad-keys: Ignore raw strings
+- 0a0ba1aa transient--do-leave: Actually behave as documented
+- ed5bd6fd transient-infix-set(argument): Fix disabling incompatible options
+- 3a2b936a Fix highlighting infix for which user input is being read
+- d834f764 transient-format(around:suffix): Don't attempt to highlight full line
+- af6eb310 transient-format: Only highlight infix if minibuffer is used
+- b1d1c369 Prevent temporary faces from leaking back into objects
+- 307695d2 transient-format-description(around:suffix): Combine faces
+- 7f0215c4 transient-format-value(option,value): Use argument faces
+
+Also contains various documentation updates and a lot of code clean-ups.
+
+This release drops support for Emacs 25.  The last Emacs 25 release
+(25.3) was released in 2017; over six years ago.  The current Emacs
+version is 29.1; that's four major releases since 25.1.
+
+* v0.4.3    2023-08-25
+
+- Added a second implementation of ~transient--wrap-command~, taking
+  advantage of improvements in Emacs 30.
+
+* v0.4.2    2023-08-25
+
+- Infix commands are only useful when invoked from a transient prefix
+  command and ~execute-extended-command~ should not offer them as
+  completion candidates.  In the past we used a weird kludge to
+  accomplish that, but now we rely on ~read-extended-command-predicate~.
+  That allowed the removal of some complications and made it possible
+  to fix a bug in ~transient--wrap-command~.
+
+  To hide infix commands, users now have to update to Emacs 28, or
+  later, and customize ~read-extended-command-predicate~.
+
+  #+begin_src emacs-lisp
+    (setq read-extended-command-predicate
+          'command-completion-default-include-p)
+  #+end_src
+
+- Due to changes in Emacs 29.1, pretty-printing isn't consistent
+  across Emacs releases anymore by default, which is unfortunate
+  in our case because we use it to write to files that are likely
+  to be checked into version control.  We now force the use of the
+  old style across releases.
+
+* v0.4.1    2023-06-02
+
+Bug fixes:
+
+- 070d47b0 Support searches that end right after suffix
+- ab831828 transient--insert-group(columns): Drop separator before first column
+- 62edeffd #247 Fix bug using :incompatible using suffixes before infixes
+- 6efa9fad transient-predicate-map: Bind univeral-argument-more
+
+* v0.4.0    2023-05-10
+
+- Transient has to update state after every suffix command.  If that
+  fails for some reason, then Emacs ends up in an badly broken state.
+  It was rare, but in the worst case scenario, that meant that Emacs
+  refused to call any more commands and had to be killed.
+
+  Naturally ~post-command-hook~ is the first choice to run something
+  after commands, but unfortunately that hook is not guaranteed to run
+  only once, and worse it is not guaranteed run /after/ the command.
+  Working around this limitation made an essential part of Transient
+  much more complex and fragile.  As new edge-cases were discovered,
+  new and increasingly desperate heuristics had to be added, until I
+  finally decided that relying solely on hooks was just not feasible.
+
+  Now ~pre-command-hook~ is used to advice ~this-command~, to add an
+  around advice, which ensures that the state update takes place, even
+  when ~post-command-hook~ is run prematurely.  The advice wraps both
+  the function body and the interactive spec with ~unwind-protect~, so
+  we can finally be sure that the state change is always performed,
+  and that the advice is removed again.
+
+  It has been an interesting journey, and I have documented it in long
+  commit messages.  If you are interested in the details, see 7b8a7d71
+  (which still tries to avoid using any advice), 51c68c87, 52cac9c0,
+  bug#61179 and bug#61176.
+
+- The ~transient-define-prefix~ now expands to code instead of data,
+  meaning that lambda expressions are finally properly evaluated and
+  byte-compiled.  ea851f3b e88f51d6 277e5f2d a1774182
+
+- Popup navigation is no longer considered a second-class feature and
+  is enabled by default.  Some transients allow arbitrary non-suffixes
+  to be invoked, so some key bindings, which were previously used for
+  popup navigation, had to be removed, to avoid conflicts.  98d50202 ff
+
+- Each prefix and suffix can now have its own help function.  This is
+  configured using the new ~show-help~ slot.  ea5ac99f
+
+- The ~transient-options~ class now supports two types of options that
+  can have multiple values: repeated option-value pairs and a final
+  option that takes all remaining arguments as value.  #154
+
+- Added support for the use of non-proportional text in the transient
+  popup.  7f5520b3
+
+- Imenu was taught about Transient's definition macros.  #178
+
+- It is now possible to return to the parent prefix from a sub-prefix.
+  e90f7a16
+
+- Boolean values of the ~transient~ slot of sub-prefixes are now
+  interpreted correctly.  4a36b1d9
+
+- Added new option ~transient-hide-during-minibuffer-read~.  5762bd9a
+
+- Added new option ~transient-align-variable-pitch~.  cda6a120
+
+- Added new command ~transient-reset~, which clears the set and saved
+  value of the active transient.  51585b8d
+
+- When using Emacs 28, ~execute-extended-command~ can be told to ignore
+  transient infix commands.  Even when using that Emacs version, that
+  command does not ignore any commands by default, but this behavior
+  can be easily be enabled using:
+
+    (setq read-extended-command-predicate
+          'command-completion-default-include-p)
+
+  Infix arguments are implemented as commands, so they by default show
+  up as completion candidates of ~execute-extended-command~, which is
+  useless because they are only intended to be invoked from transient
+  prefix commands.  Enable this feature to prevent that.
+
+- Added new command ~transient-toggle-debug~.  b466cd9a
+
+- Depend on the Compat package, allowing me to use convenient features
+  that were added to Emacs over the last few years, without having to
+  wait another few years until everybody has updated to a reasonably
+  recent Emacs release.  5ae3c401
+
+- Added basic support for suffixes that span multiple lines (multi-row
+  cells).  #193
+
+- Infix arguments can now be invoked following a prefix argument.  To
+  use a negative prefix argument use "C--".  "-" cannot be used anymore
+  because it conflicts with the most common prefix key used for infix
+  arguments.  ed2febd0
+
+- Removed obsolete aliases for functions deprecated in v0.3.0.  #192
+
+- Duplicated suffix commands are now disambiguated, making it possible
+  to bind a command multiple times as a suffix of a transient command,
+  but still have it do different things depending on what binding is
+  used, based on the value of some slot of the corresponding suffix
+  object, similar to how ~self-insert-command~ inserts the pressed key.
+  f27c840a
+
+- ~recursive-edit~ and ~top-level~ can now be used while a transient is
+  active.  fcdeadc1 5a1b2bac
+
+- Switched to Emacs 29's new keymap functions, which are also supported
+  in newer releases, thanks to the Compat package.  87f70af5 5a966aa8

+
+Also contains various documentation updates, code clean-ups and
+build improvements.
+
+* v0.3.7    2021-10-25
+
+- Added an additional safety hatch to prevent Emacs from entering an
+  inconsistent state when an unexpected error occurs.  99e48369
+
+- Added support for implementing section movement commands in
+  third-party packages.  This was requested by the maintainer of
+  Emacspeak.  Because they would be of very limited use to sighted
+  users no such commands are added to Transient itself.  769219b5
+
+- ~transient-read-number-{N0,N+,N}~ now support infix arguments that
+  have three different states: disabled, enabled without an empty
+  value, and enabled with a non-empty value.  626d105e
+
+- If a command is called as a suffix of itself, then the help command
+  shows the function definition instead of the man-page as it usually
+  does for prefixes.  e17e2b2f
+
+- Give users more control over how the transient buffer is displayed.
+  Various aspects that were previously hardcoded can now be changed
+  using the ~transient-display-buffer-action~ option.  7c677737
+
+- Added support for adding suffixes that might be neither defined nor
+  autoloaded when the prefix is invoked.  This usually results in an
+  error and while it is now possible to override that using an extra
+  step, it is still discouraged.  6842305e
+
+Bug fixes:
+
+- 1e740608 transient-map: Bind C-u to universal-argument
+- e9048100 Explicitly call transient--pre-command in button action

+- b526b9c7 transient-infix-set: Consider all incompatibility rules
+- 7126d6aa Fix hydra-inspired colors
+- 0c2255a2 transient-get-value: Add an emergency exit
+
+Also contains various documentation updates and code clean-ups.
+
+* v0.3.6    2021-07-01
+
+- Added new option ~transient-force-single-column~, which may be useful
+  for low vision.  #122
+
+- Added new option ~transient-highlight-higher-levels~, which is
+  intended for package authors.  90a05622
+
+* v0.3.5    2021-06-16
+
+- Added a kludge to work around some unexpected Emacs behavior.
+  ef921d30
+
+- When showing help for a suffix that is also a subprefix, then also
+  consider the manpage that is set for the prefix, if any.  a9bdd013
+
+* v0.3.4    2021-05-25
+
+- Very minor changes.
+
+* v0.3.3    2021-05-24
+
+- Added SPDX-License-Identifier library header.  7d3d8d79
+
+* v0.3.2    2021-04-20
+
+- Fixed an error message.  c145229a
+
+* v0.3.1    2021-04-19
+
+- Changed ~transient-prefix~'s ~suffix-description~ slot to be initially
+  unbound, as was always intended.  c28b8a4
+
+- Added new functions ~transient-read-file~ and
+  ~transient-read-existing-file~.  a3b44224
+
+* v0.3.0    2021-02-21
+
+- Added a temporary kludge to prevent a transient from being invoked
+  while the minibuffer is active.  A future release will enable
+  this again, once we are sure that cannot cause Emacs to enter an
+  inconsistent state, that causes most events to be ignored.  #112
+
+- Improved the backtrace that is shown when a fatal error occurred in a
+  critical context.  This involved some back and forth.  See commits
+  mentioning the "emergency exit".
+
+- Added support for defining a per-prefix fallback suffix description
+  function, which is used for suffixes that do not explicitly provide
+  a description.  The new ~suffix-description~ slot is used to specify
+  that function.  The new ~transient-command-summary-or-name~ function
+  is useful, not just as an example.  8b22b52b
+
+- Added ~transient-arg-value~, which can be used to extract the values
+  of individual arguments in the output of ~transient-args~.  d76f73f8
+
+- Added support for using variables in group and suffix definitions
+  of a prefix.  Such indirect specifications are resolved when the
+  transient prefix is being defined.  #101
+
+- No longer bind ~M-<key>~ to any common suffix commands; freeing this
+  namespace for a variety of uses in individual transient.  A few
+  existing bindings had to be changed because of this.  990eb0a2
+
+- Added ~transient-suffixes~ function, which is useful when
+  ~transient-args~ is not sufficient because one needs the suffix
+  objects, not just their values.  #98
+
+- Added ~init-value~ slot for infix and prefix objects.  If this value
+  bound then it is called with the object as only argument instead of
+  the primary ~transient-init-value~ method of the object class.  #96,
+  3284f6a0
+
+- Added ~unsavable~ slot for infix objects.  If this is non-nil, then
+  the value of the infix is removed from the prefix value before
+  saving, setting and adding to history.  #96
+
+- Added support for right padding the keys of all suffixes in a group.
+  This is controlled using the new ~pad-keys~ slot of group objects.
+  7502390b, 293a437d
+
+- Added support for delaying setup of the suffixes of a prefix until
+  that is invoked.  Also added support for using unnamed functions as
+  suffix commands.  Taken together these changes make it possible to
+  dynamically create the list of suffixed.  See the ~notmuch-transient~
+  package for two examples: ~notmuch-search-transient~ and
+  ~notmuch-tag-transient~.  f2252d53, a3e53633
+
+- Added the infix class ~transient-lisp-variable~.  2d8ceff4
+
+- Added ~transient-infix-read~, which allows arbitrary commands to read
+  a value the same way as would the infix command that is provided as
+  an argument to this function.  73694be4
+
+- Added support for coloring suffixes in a Hydra-like fashion.
+  To enable this, customize option ~transient-semantic-coloring~.
+  248862c5
+
+- Added support for disabling and dimming suffix commands that are
+  currently not suitable, instead of completely hiding them.  #80
+
+- Autoload functions that serve a purpose similar to that of
+  ~define-key~. #85
+
+- Consistently use ~transient-~ as the prefix of all symbols.
+  The old names remain available as obsolete aliases.  dd0c44cb
+
+- Added support for scrolling the transient popup buffer using the
+  scroll bar.  #84
+
+- Various bug fixes.
+  48238bf5 Allow invoking arbitrary prefixes as non-suffixes
+  d85eb790 transient-read-directory: Pass read value through file-local-name
+  f086cb62 transient--insert-suffix: Allow same key with different predicates
+  d555d260 transient-format-description(lisp-variable): Return string
+  0d79ccfa transient--parse-suffix: Don't fallback to read-string for options
+  f88dbc43 transient-suffix-object: Support all suffixes
+  b343e2a3 transient-infix-read: Fix ivy specific kludge
+  55bad195 transient--pp-to-file: Bugfix
+  c1df3b21 Ensure we use symbols in a few more places
+  769fa438 transient-set-level: Fix edge-case
+  88d935c7 transient-display-buffer-action: inhibit-same-window by default
+
+* v0.2.0    2020-02-26
+
+- ~transient-args~ must now be called with a transient prefix command
+  as argument.  It is now the only argument and its value must be a
+  symbol now, an object is no longer supported.  When this command
+  does not match ~current-transient-command~, then this function now
+  returns the set, saved or default value.  0312b93, 7d0db28,
+  d33fe5a, a6ce195
+
+- No longer use the last history element as initial minibuffer input
+  by default.  Added new option ~transient-read-with-initial-input~ to
+  allow users to restore the old default. dcf7a4d, 5decc6e
+
+- The set and saved values were not always used.  #68
+
+- Added support for inserting and removing groups.  #36
+
+- Added support for specifying where to insert elements and groups
+  using coordinates.  #26
+
+- Added support for moving the cursor inside the transient popup
+  buffer using the arrow keys or Isearch, and for invoke suffix
+  commands using RET or mouse clicks.  Unlike Magit-Popup, Transient
+  doesn't make the transient popup buffer the current buffer.  This
+  is important when invoking suffix commands that take the current
+  position into account, but it has the drawback that we do not get
+  these features for free.  Because I also consider them unnecessary
+  I did not implement them initially.  Turns out quite a few users
+  strongly disagree.  Set ~transient-enable-popup-navigation~ to ~t~ to
+  enable these features.  #42
+
+- Explicitly support Edebug.  Previously when Edebug was triggered
+  while a transient was active, then Emacs entered an unrecoverable
+  state.  #19
+
+- No longer attempt to display a thin line in termcap frames.  0a96a57
+
+- Work around some Ivy bugs/incompatibilities.  af243d5, fed7ab1
+
+- The new option ~transient-force-fixed-pitch~ allows users to use a
+  monospaced font in transient's popup buffer even if they use a
+  proportional font for the rest of Emacs.  #25, #67
+
+- Adapted to backward incompatible changes in Emacs 27 that prevented
+  faces from extending to the edge of the window as expected.  c1ae1ee
+
+- No longer depend on dash (or any other third-party package).  #66
+
+- When a transient has conflicting key bindings and Transient is
+  configure to warn about that, then Emacs entered an unrecoverable
+  state instead.  75de1f0
+
+- ~transient-format-value~ now supports options with multiple values.
+  #65
+
+- Removing a suffix based on its position was broken.  41cbf49
+
+- In our popup buffers disable the tab feature that Emacs 27
+  introduces.  #62
+
+- Inserting a new suffix next to another ended up replacing the latter
+  instead if its key binding was defined in the suffix object.  #58
+
+- ~transient-undefined~ learned to make some noise.  #57
+
+- Fix replacing a suffix with another suffix bound to the same key.
+  5a360bb, 4ce1868
+
+- Characters are no longer allowed as pseudo suffixes.  To insert a
+  an empty cell into a table use the empty string instead.  71687ba
+
+- Added new variable ~transient--buffer-name~.  #45
+
+- Some misconfiguration that affects how the transient popup buffer
+  is displayed could lead to Emacs entering an unrecoverable state.
+  #34, #44
+
+- The echo area is now cleared when the transient popup buffer is
+  shown.  afdf1f0
+
+- If ~transient-show-popup~ is 0 or a negative number, then not even
+  a one-line summary is shown initially.  #41
+
+- Added new function ~transient-read-directory~.  a87cb2c
+
+- ~define-transient-command~ now supports specifying the level of a
+  suffix using the ~:level~ keyword argument.  6506cfd
+
+- The mode-related suffix predicates now also support a list of modes
+  as argument in addition to a single mode as before.  1c6afb8
+
+- The new ~incompatible~ slot of prefix objects makes it possible to
+  specify which arguments should be autoatically disabled when the
+  user enables certain other arguments.  544b3bb
+
+- ~transient--history-push~ is now defined as generic function.  47b7975
+
+- The a new ~history-key~ slot and ~transient--history-key~ generic
+  function for prefix objects.  3668aeb, e627d45
+
+- Disallow setting the level of essential suffixes that are shared
+  between all transients.  #29
+
+- The active infix is now highlight while reading its value from the
+  user.  #30
+
+- The commands ~transient-set~  and ~transient-save~ can now be configured
+  to exit the transient, though by default they still don't.  a47ae94
+
+- Always respect the ~transient~ slot of a suffix, even if that suffix
+  has a binding in ~transient-predicate-map~.  919fc66
+
+- Added new generic functions ~transient-set-value~ and
+  ~transient-save-value~ intended for prefix commands.  ebe9d9d
+
+- It is no longer possible to set a prefix level to 0, which is an
+  invalid value.  #28
+
+- All transient prefix and suffix commands are now automatically
+  declared to be for interactive use only.  a6295fa
+
+- Infix arguments are no longer added to ~command-history~ because
+  these entries were both useless and extremely noisy.  #23
+
+- ~digit-argument~ no longer exits the transient.  5f0ec7d
+
+- A new keymap, ~transient-base-map~ was added to make it easier to
+  change key bindings that are shared between all transients.  This
+  new keymap is used as the parent of all the other keymaps that are
+  shared between all transients.
+
+- Added new commands ~transient-scroll-up~ and ~transient-scroll-down~,
+  which scroll the transient window.  ~C-v~ and ~M-v~ (and ~<next>~ and
+  ~<prior>~) are bound to these commands.  These keys were chosen they
+  are bound to scrolling commands in the global map too.  This made
+  it necessary to find a new binding for ~transient-show~, which ~C-t~ is
+  bound to now.  #17
+
+- The new option ~transient-mode-line-format~ allows users to use
+  a mode-line for the transient popup buffer instead of just a
+  thin line that separates it from the echo area.  When using a
+  non-standard value for ~transient-display-buffer-action~ it may
+  be necessary to do that.  #17
+
+- The new option ~transient-display-buffer-action~ allows users to
+  specify how a window is selected to display the transient popup
+  buffer.  The ~lv~ library is no longer used.  #17
+
+- The window that was selected before the transient window was shown
+  is no longer re-selected before calling a suffix that exits the
+  transient.  If a suffix changes the selected window unintentionally,
+  then that is a bug.  This makes it possible to intentionally change
+  the window layout using transients.
+
+- An infix is a special kind of suffix.  Depending on context
+  "suffixes" means "suffixes (including infixes)" or "non-infix
+  suffixes".  This is now mention in a few places where users might
+  otherwise get confused.
+
+- Stopped claiming that the transient is shown in the "echo area",
+  because technically that is not correct.  Instead talk about the
+  "popup buffer".
+
+- Fixed handling of suffix commands that are undefined at the time the
+  prefix is invoked.  This is still an error, but the error message
+  now explains what is wrong.  a729bbb
+
+- Fixed saving values/history/levels, making sure that the printed
+  expression is never abbreviated.  #15
+
+- Fixed jumping to the correct place in a manpage when showing the
+  documentation for an infix argument.  c4bf4af
+
+- Bound ~ESC ESC ESC~ to ~transient-quit-all~ because the convention is
+  that it should be possible to exit any temporary state using this
+  binding.  #12
+
+- Fixed referencing suffix bindings by their key when the key binding
+  is defined in the suffix object instead of in the suffix spec.
+  e4ffb97
+
+- Remove trailing whitespace from popup text for the benefit of users
+  who have set enabled ~show-trailing-whitespace~ globally.  0758efa
+
+- Fixed showing available bindings on a single line instead of using
+  the usual popup buffer.  2f011c9, 99d3bf6
+
+- Added a line between the ~lv~ window and the echo area.  ca18bb6
+
+- Fixed adding a new suffix at the end of a group and removing a
+  group's last suffix.  #20, #6
+
+- No longer use ~cl-typep~, which appears to have a bug on Emacs 25.
+  9183fe1
+
+- Fixed ~lisp~ make target.  170a3fd
+
+- Fixed reading a number as the value of an infix.  8219c0b
+
+- Various bug fixes to
+  ~transient--goto-argument-description~ (4f80a89),
+  ~transient-show-help~ (ccac95e),
+  ~transient-infix-read~ (7bf9759).

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+1 Transient command menus
+═════════════════════════
+
+  Transient is the library used to implement the keyboard-driven “menus”
+  in [Magit].  It is distributed as a separate package, so that it can
+  be used to implement similar menus in [other packages].
+
+
+[Magit] <https://github.com/magit/magit/>
+
+[other packages] <https://melpa.org/#/transient>
+
+1.1 Some things that Transient can do
+─────────────────────────────────────
+
+  • Display current state of arguments
+  • Display and manage lifecycle of modal bindings
+  • Contextual user interface
+  • Flow control for wizard-like composition of interactive forms
+  • History & persistence
+  • Rendering arguments for controlling CLI programs
+
+
+1.2 Complexity in CLI programs
+──────────────────────────────
+
+  Complexity tends to grow with time.  How do you manage the complexity
+  of commands?  Consider the humble shell command `ls'.  It now has over
+  /fifty/ command line options.  Some of these are boolean flags (`ls
+  -l').  Some take arguments (`ls --sort=s').  Some have no effect
+  unless paired with other flags (`ls -lh').  Some are mutually
+  exclusive.  Some shell commands even have so many options that they
+  introduce /subcommands/ (`git branch', `git commit'), each with their
+  own rich set of options (`git branch -f').
+
+
+1.3 Using Transient for composing interactive commands
+──────────────────────────────────────────────────────
+
+  What about Emacs commands used interactively? How do these handle
+  options?  One solution is to make many versions of the same command,
+  so you don't need to! Consider: `delete-other-windows' vs.
+  `delete-other-windows-vertically' (among many similar examples).
+
+  Some Emacs commands will simply prompt you for the next "argument"
+  (`M-x switch-to-buffer').  Another common solution is to use prefix
+  arguments which usually start with `C-u'.  Sometimes these are
+  sensibly numerical in nature (`C-u 4 M-x forward-paragraph' to move
+  forward 4 paragraphs).  But sometimes they function instead as boolean
+  "switches" (`C-u C-SPACE' to jump to the last mark instead of just
+  setting it, `C-u C-u C-SPACE' to unconditionally set the mark).  Since
+  there aren't many standards for the use of prefix options, you have to
+  read the command's documentation to find out what the possibilities
+  are.
+
+  But when an Emacs command grows to have a truly large set of options
+  and arguments, with dependencies between them, lots of option values,
+  etc., these simple approaches just don't scale.  Transient is designed
+  to solve this issue.  Think of it as the humble prefix argument `C-u',
+  /raised to the power of 10/.  Like `C-u', it is key driven.  Like the
+  shell, it supports boolean "flag" options, options that take
+  arguments, and even "sub-commands", with their own options.  But
+  instead of searching through a man page or command documentation,
+  well-designed transients /guide/ their users to the relevant set of
+  options (and even their possible values!) directly, taking into
+  account any important pre-existing Emacs settings.  And while for
+  shell commands like `ls', there is only one way to "execute" (hit
+  `Return'!), transients can "execute" using multiple different keys
+  tied to one of many self-documenting /actions/ (imagine having 5
+  different colored return keys on your keyboard!).  Transients make
+  navigating and setting large, complex groups of command options and
+  arguments easy.  Fun even.  Once you've tried it, it's hard to go back
+  to the `C-u what can I do here again?' way.

+
+@display
+Copyright @copyright{} 2007 Free Software Foundation, Inc. @url{https://fsf.org/}
+

+license document, but changing it is not allowed.
+@end display
+
+@heading Preamble
+
+The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom
+to share and change all versions of a program---to make sure it remains
+free software for all its users.  We, the Free Software Foundation,
+use the GNU General Public License for most of our software; it
+applies also to any other work released this way by its authors.  You
+can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you
+have certain responsibilities if you distribute copies of the
+software, or if you modify it: responsibilities to respect the freedom
+of others.
+
+For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too,
+receive or can get the source code.  And you must show them these
+terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the
+manufacturer can do so.  This is fundamentally incompatible with the
+aim of protecting users' freedom to change the software.  The
+systematic pattern of such abuse occurs in the area of products for
+individuals to use, which is precisely where it is most unacceptable.
+Therefore, we have designed this version of the GPL to prohibit the
+practice for those products.  If such problems arise substantially in
+other domains, we stand ready to extend this provision to those
+domains in future versions of the GPL, as needed to protect the
+freedom of users.
+
+Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish
+to avoid the special danger that patents applied to a free program
+could make it effectively proprietary.  To prevent this, the GPL
+assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+@heading TERMS AND CONDITIONS
+
+@enumerate 0
+@item Definitions.
+
+``This License'' refers to version 3 of the GNU General Public License.
+
+``Copyright'' also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+
+``The Program'' refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as ``you''.  ``Licensees'' and
+``recipients'' may be individuals or organizations.
+
+To ``modify'' a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of
+an exact copy.  The resulting work is called a ``modified version'' of
+the earlier work or a work ``based on'' the earlier work.
+
+A ``covered work'' means either the unmodified Program or a work based
+on the Program.
+
+To ``propagate'' a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To ``convey'' a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user
+through a computer network, with no transfer of a copy, is not
+conveying.
+
+An interactive user interface displays ``Appropriate Legal Notices'' to
+the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+@item Source Code.
+
+The ``source code'' for a work means the preferred form of the work for
+making modifications to it.  ``Object code'' means any non-source form
+of a work.
+
+A ``Standard Interface'' means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The ``System Libraries'' of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+``Major Component'', in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The ``Corresponding Source'' for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can
+regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same
+work.
+
+@item Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey,
+without conditions so long as your license otherwise remains in force.
+You may convey covered works to others for the sole purpose of having
+them make modifications exclusively for you, or provide you with
+facilities for running those works, provided that you comply with the
+terms of this License in conveying all material for which you do not
+control copyright.  Those thus making or running the covered works for
+you must do so exclusively on your behalf, under your direction and
+control, on terms that prohibit them from making any copies of your
+copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the
+conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+@item Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such
+circumvention is effected by exercising rights under this License with
+respect to the covered work, and you disclaim any intention to limit
+operation or modification of the work as a means of enforcing, against
+the work's users, your or third parties' legal rights to forbid
+circumvention of technological measures.
+
+@item Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+@item Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these
+conditions:
+
+@enumerate a
+@item
+The work must carry prominent notices stating that you modified it,
+and giving a relevant date.
+
+@item
+The work must carry prominent notices stating that it is released
+under this License and any conditions added under section 7.  This
+requirement modifies the requirement in section 4 to ``keep intact all
+notices''.
+
+@item
+You must license the entire work, as a whole, under this License to
+anyone who comes into possession of a copy.  This License will
+therefore apply, along with any applicable section 7 additional terms,
+to the whole of the work, and all its parts, regardless of how they
+are packaged.  This License gives no permission to license the work in
+any other way, but it does not invalidate such permission if you have
+separately received it.
+
+@item
+If the work has interactive user interfaces, each must display
+Appropriate Legal Notices; however, if the Program has interactive
+interfaces that do not display Appropriate Legal Notices, your work
+need not make them do so.
+@end enumerate
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+``aggregate'' if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+@item  Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of
+sections 4 and 5, provided that you also convey the machine-readable
+Corresponding Source under the terms of this License, in one of these
+ways:
+
+@enumerate a
+@item
+Convey the object code in, or embodied in, a physical product
+(including a physical distribution medium), accompanied by the
+Corresponding Source fixed on a durable physical medium customarily
+used for software interchange.
+
+@item
+Convey the object code in, or embodied in, a physical product
+(including a physical distribution medium), accompanied by a written
+offer, valid for at least three years and valid for as long as you
+offer spare parts or customer support for that product model, to give
+anyone who possesses the object code either (1) a copy of the
+Corresponding Source for all the software in the product that is
+covered by this License, on a durable physical medium customarily used
+for software interchange, for a price no more than your reasonable
+cost of physically performing this conveying of source, or (2) access
+to copy the Corresponding Source from a network server at no charge.
+
+@item
+Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source.  This alternative is
+allowed only occasionally and noncommercially, and only if you
+received the object code with such an offer, in accord with subsection
+6b.
+
+@item
+Convey the object code by offering access from a designated place
+(gratis or for a charge), and offer equivalent access to the
+Corresponding Source in the same way through the same place at no
+further charge.  You need not require recipients to copy the
+Corresponding Source along with the object code.  If the place to copy
+the object code is a network server, the Corresponding Source may be
+on a different server (operated by you or a third party) that supports
+equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source.
+Regardless of what server hosts the Corresponding Source, you remain
+obligated to ensure that it is available for as long as needed to
+satisfy these requirements.
+
+@item
+Convey the object code using peer-to-peer transmission, provided you
+inform other peers where the object code and Corresponding Source of
+the work are being offered to the general public at no charge under
+subsection 6d.
+
+@end enumerate
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A ``User Product'' is either (1) a ``consumer product'', which means any
+tangible personal property which is normally used for personal,
+family, or household purposes, or (2) anything designed or sold for
+incorporation into a dwelling.  In determining whether a product is a
+consumer product, doubtful cases shall be resolved in favor of
+coverage.  For a particular product received by a particular user,
+``normally used'' refers to a typical or common use of that class of
+product, regardless of the status of the particular user or of the way
+in which the particular user actually uses, or expects or is expected
+to use, the product.  A product is a consumer product regardless of
+whether the product has substantial commercial, industrial or
+non-consumer uses, unless such uses represent the only significant
+mode of use of the product.
+
+``Installation Information'' for a User Product means any methods,
+procedures, authorization keys, or other information required to
+install and execute modified versions of a covered work in that User
+Product from a modified version of its Corresponding Source.  The
+information must suffice to ensure that the continued functioning of
+the modified object code is in no case prevented or interfered with
+solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or
+updates for a work that has been modified or installed by the
+recipient, or for the User Product in which it has been modified or
+installed.  Access to a network may be denied when the modification
+itself materially and adversely affects the operation of the network
+or violates the rules and protocols for communication across the
+network.
+
+Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+@item Additional Terms.
+
+``Additional permissions'' are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders
+of that material) supplement the terms of this License with terms:
+
+@enumerate a
+@item
+Disclaiming warranty or limiting liability differently from the terms
+of sections 15 and 16 of this License; or
+
+@item
+Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices
+displayed by works containing it; or
+
+@item
+Prohibiting misrepresentation of the origin of that material, or
+requiring that modified versions of such material be marked in
+reasonable ways as different from the original version; or
+
+@item
+Limiting the use for publicity purposes of names of licensors or
+authors of the material; or
+
+@item
+Declining to grant rights under trademark law for use of some trade
+names, trademarks, or service marks; or
+
+@item
+Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with
+contractual assumptions of liability to the recipient, for any
+liability that these contractual assumptions directly impose on those
+licensors and authors.
+@end enumerate
+
+All other non-permissive additional terms are considered ``further
+restrictions'' within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions; the
+above requirements apply either way.
+
+@item Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+@item Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run
+a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+@item Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+An ``entity transaction'' is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+@item Patents.
+
+A ``contributor'' is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's ``contributor version''.
+
+A contributor's ``essential patent claims'' are all patent claims owned
+or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, ``control'' includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a ``patent license'' is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To ``grant'' such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  ``Knowingly relying'' means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is ``discriminatory'' if it does not include within the
+scope of its coverage, prohibits the exercise of, or is conditioned on
+the non-exercise of one or more of the rights that are specifically
+granted under this License.  You may not convey a covered work if you
+are a party to an arrangement with a third party that is in the
+business of distributing software, under which you make payment to the
+third party based on the extent of your activity of conveying the
+work, and under which the third party grants, to any of the parties
+who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by
+you (or copies made from those copies), or (b) primarily for and in
+connection with specific products or compilations that contain the
+covered work, unless you entered into that arrangement, or that patent
+license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+@item No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey
+a covered work so as to satisfy simultaneously your obligations under
+this License and any other pertinent obligations, then as a
+consequence you may not convey it at all.  For example, if you agree
+to terms that obligate you to collect a royalty for further conveying
+from those to whom you convey the Program, the only way you could
+satisfy both those terms and this License would be to refrain entirely
+from conveying the Program.
+
+@item Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+@item Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions
+of the GNU General Public License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies that a certain numbered version of the GNU General Public
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that numbered version or
+of any later version published by the Free Software Foundation.  If
+the Program does not specify a version number of the GNU General
+Public License, you may choose any version ever published by the Free
+Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions
+of the GNU General Public License can be used, that proxy's public
+statement of acceptance of a version permanently authorizes you to
+choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+@item Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW@.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+A PARTICULAR PURPOSE@.  THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU@.  SHOULD THE PROGRAM PROVE
+DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+@item Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
+LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
+TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+@item Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+@end enumerate
+
+@heading END OF TERMS AND CONDITIONS
+
+@heading How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.
+
+@smallexample
+@var{one line to give the program's name and a brief idea of what it does.}

+The hypothetical commands @samp{show w} and @samp{show c} should show
+the appropriate parts of the General Public License.  Of course, your
+program's commands might be different; for a GUI interface, you would
+use an ``about box''.
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a ``copyright disclaimer'' for the program, if necessary.

+
+The transient popup buffer is displayed in a window using
+
+  (display-buffer BUFFER transient-display-buffer-action)
+
+The value of this option has the form (FUNCTION . ALIST),
+where FUNCTION is a function or a list of functions.  Each such
+function should accept two arguments: a buffer to display and an
+alist of the same form as ALIST.  See info node `(elisp)Choosing
+Window' for details.
+
+The default is:
+
+  (display-buffer-in-side-window
+    (side . bottom)
+    (dedicated . t)
+    (inhibit-same-window . t))
+
+This displays the window at the bottom of the selected frame.
+For alternatives see info node `(elisp)Display Action Functions'
+and info node `(elisp)Buffer Display Action Alists'.
+
+When you switch to a different ACTION, you should keep the ALIST
+entries for `dedicated' and `inhibit-same-window' in most cases.
+Do not drop them because you are unsure whether they are needed;
+if you are unsure, then keep them.
+
+Note that the buffer that was current before the transient buffer
+is shown should remain the current buffer.  Many suffix commands
+act on the thing at point, if appropriate, and if the transient
+buffer became the current buffer, then that would change what is
+at point.  To that effect `inhibit-same-window' ensures that the
+selected window is not used to show the transient buffer.
+
+The use of a horizontal split to display the menu window can lead
+to incompatibilities and is thus discouraged.  Transient tries to
+mitigate such issue but cannot proactively deal with all possible
+configurations and combinations of third-party packages.
+
+It may be possible to display the window in another frame, but
+whether that works in practice depends on the window-manager.

+At least one key-value pair is required.  All transient infix

+less to define an infix command, without providing at least one
+keyword argument (usually `:argument' or `:variable', depending

+**************
+
+Transient is the library used to implement the keyboard-driven “menus”
+in Magit.  It is distributed as a separate package, so that it can be
+used to implement similar menus in other packages.
+
+   This manual can be bit hard to digest when getting started.  A useful
+resource to get over that hurdle is Psionic K’s interactive tutorial,
+available at <https://github.com/positron-solutions/transient-showcase>.
+
+Some things that Transient can do
+=================================
+
+   • Display current state of arguments
+   • Display and manage lifecycle of modal bindings
+   • Contextual user interface
+   • Flow control for wizard-like composition of interactive forms
+   • History & persistence
+   • Rendering arguments for controlling CLI programs
+
+Complexity in CLI programs
+==========================
+
+Complexity tends to grow with time.  How do you manage the complexity of
+commands?  Consider the humble shell command ‘ls’.  It now has over
+_fifty_ command line options.  Some of these are boolean flags (‘ls
+-l’).  Some take arguments (‘ls --sort=s’).  Some have no effect unless
+paired with other flags (‘ls -lh’).  Some are mutually exclusive.  Some
+shell commands even have so many options that they introduce
+_subcommands_ (‘git branch’, ‘git commit’), each with their own rich set
+of options (‘git branch -f’).
+
+Using Transient for composing interactive commands
+==================================================
+
+What about Emacs commands used interactively?  How do these handle
+options?  One solution is to make many versions of the same command, so
+you don’t need to!  Consider: ‘delete-other-windows’ vs.
+‘delete-other-windows-vertically’ (among many similar examples).
+
+   Some Emacs commands will simply prompt you for the next "argument"
+(‘M-x switch-to-buffer’).  Another common solution is to use prefix
+arguments which usually start with ‘C-u’.  Sometimes these are sensibly
+numerical in nature (‘C-u 4 M-x forward-paragraph’ to move forward 4
+paragraphs).  But sometimes they function instead as boolean "switches"
+(‘C-u C-SPACE’ to jump to the last mark instead of just setting it, ‘C-u
+C-u C-SPACE’ to unconditionally set the mark).  Since there aren’t many
+standards for the use of prefix options, you have to read the command’s
+documentation to find out what the possibilities are.
+
+   But when an Emacs command grows to have a truly large set of options
+and arguments, with dependencies between them, lots of option values,
+etc., these simple approaches just don’t scale.  Transient is designed
+to solve this issue.  Think of it as the humble prefix argument ‘C-u’,
+_raised to the power of 10_.  Like ‘C-u’, it is key driven.  Like the
+shell, it supports boolean "flag" options, options that take arguments,
+and even "sub-commands", with their own options.  But instead of
+searching through a man page or command documentation, well-designed
+transients _guide_ their users to the relevant set of options (and even
+their possible values!)  directly, taking into account any important
+pre-existing Emacs settings.  And while for shell commands like ‘ls’,
+there is only one way to "execute" (hit ‘Return’!), transients can
+"execute" using multiple different keys tied to one of many
+self-documenting _actions_ (imagine having 5 different colored return
+keys on your keyboard!).  Transients make navigating and setting large,
+complex groups of command options and arguments easy.  Fun even.  Once
+you’ve tried it, it’s hard to go back to the ‘C-u what can I do here
+again?’ way.

+
+2.1 Invoking Transients
+=======================
+
+A transient prefix command is invoked like any other command by pressing
+the key that is bound to that command.  The main difference to other
+commands is that a transient prefix command activates a transient
+keymap, which temporarily binds the transient’s infix and suffix
+commands, and that those bindings are displayed in a transient menu,
+displayed in a popup buffer.  Bindings from other keymaps may, or may
+not, be disabled while the transient state is in effect.
+
+   There are two kinds of commands that are available after invoking a
+transient prefix command; infix and suffix commands.  Infix commands set
+some value (which is then shown in the popup buffer), without leaving
+the transient.  Suffix commands, on the other hand, usually quit the
+transient and they may use the values set by the infix commands, i.e.,
+the infix *arguments*.
+
+   Instead of setting arguments to be used by a suffix command, infix
+commands may also set some value by side-effect, e.g., by setting the
+value of some variable.
+
+
+File: doccZhEUk.info,  Node: Aborting and Resuming Transients,  Next: Common Suffix Commands,  Prev: Invoking Transients,  Up: Usage
+
+2.2 Aborting and Resuming Transients
+====================================
+
+To quit the transient without invoking a suffix command press ‘C-g’.
+
+   Key bindings in transient keymaps may be longer than a single event.
+After pressing a valid prefix key, all commands whose bindings do not
+begin with that prefix key are temporarily unavailable and grayed out.
+To abort the prefix key press ‘C-g’ (which in this case only quits the
+prefix key, but not the complete transient).
+
+   A transient prefix command can be bound as a suffix of another
+transient.  Invoking such a suffix replaces the current transient state
+with a new transient state, i.e., the available bindings change and the
+information displayed in the popup buffer is updated accordingly.
+Pressing ‘C-g’ while a nested transient is active only quits the
+innermost transient, causing a return to the previous transient.
+
+   ‘C-q’ or ‘C-z’ on the other hand always exits all transients.  If you
+use the latter, then you can later resume the stack of transients using
+‘M-x transient-resume’.
+
+Key: C-g (transient-quit-seq)
+
+Key: C-g (transient-quit-one)
+     This key quits the currently active incomplete key sequence, if
+     any, or else the current transient.  When quitting the current
+     transient, it returns to the previous transient, if any.
+
+   Transient’s predecessor bound ‘q’ instead of ‘C-g’ to the quit
+command.  To learn how to get that binding back see
+‘transient-bind-q-to-quit’’s documentation string.
+
+Key: C-q (transient-quit-all)
+     This command quits the currently active incomplete key sequence, if
+     any, and all transients, including the active transient and all
+     suspended transients, if any.
+
+Key: C-z (transient-suspend)
+     Like ‘transient-quit-all’, this command quits an incomplete key
+     sequence, if any, and all transients.  Additionally, it saves the
+     stack of transients so that it can easily be resumed (which is
+     particularly useful if you quickly need to do “something else” and
+     the stack is deeper than a single transient, and/or you have
+     already changed the values of some infix arguments).
+
+     Note that only a single stack of transients can be saved at a time.
+     If another stack is already saved, then saving a new stack discards
+     the previous stack.
+
+Key: M-x transient-resume
+     This command resumes the previously suspended stack of transients,
+     if any.
+
+
+File: doccZhEUk.info,  Node: Common Suffix Commands,  Next: Saving Values,  Prev: Aborting and Resuming Transients,  Up: Usage
+
+2.3 Common Suffix Commands
+==========================
+
+A few shared suffix commands are available in all transients.  These
+suffix commands are not shown in the popup buffer by default.
+
+   This includes the aborting commands mentioned in the previous
+section, as well as some other commands that are all bound to ‘C-x KEY’.
+After ‘C-x’ is pressed, a section featuring all these common commands is
+temporarily shown in the popup buffer.  After invoking one of them, the
+section disappears again.  Note, however, that one of these commands is
+described as “Show common permanently”; invoke that if you want the
+common commands to always be shown for all transients.
+
+Key: C-x t (transient-toggle-common)
+     This command toggles whether the generic commands that are common
+     to all transients are always displayed or only after typing the
+     incomplete prefix key sequence ‘C-x’.  This only affects the
+     current Emacs session.
+
+User Option: transient-show-common-commands
+     This option controls whether shared suffix commands are shown
+     alongside the transient-specific infix and suffix commands.  By
+     default, the shared commands are not shown to avoid overwhelming
+     the user with too many options.
+
+     While a transient is active, pressing ‘C-x’ always shows the common
+     commands.  The value of this option can be changed for the current
+     Emacs session by typing ‘C-x t’ while a transient is active.
+
+   The other common commands are described in either the previous or in
+one of the following sections.
+
+
+File: doccZhEUk.info,  Node: Saving Values,  Next: Using History,  Prev: Common Suffix Commands,  Up: Usage
+
+2.4 Saving Values
+=================
+
+After setting the infix arguments in a transient, the user can save
+those arguments for future invocations.
+
+   Most transients will start out with the saved arguments when they are
+invoked.  There are a few exceptions, though.  Some transients are
+designed so that the value that they use is stored externally as the
+buffer-local value of some variable.  Invoking such a transient again
+uses the buffer-local value.  (1)
+
+   If the user does not save the value and just exits using a regular
+suffix command, then the value is merely saved to the transient’s
+history.  That value won’t be used when the transient is next invoked,
+but it is easily accessible (see *note Using History::).
+
+Key: C-x s (transient-set)
+     This command saves the value of the active transient for this Emacs
+     session.
+
+Key: C-x C-s (transient-save)
+     This command saves the value of the active transient persistently
+     across Emacs sessions.
+
+Key: C-x C-k (transient-reset)
+     This command clears the set and saved values of the active
+     transient.
+
+User Option: transient-values-file
+     This option names the file that is used to persist the values of
+     transients between Emacs sessions.
+
+   ---------- Footnotes ----------
+
+   (1) ‘magit-diff’ and ‘magit-log’ are two prominent examples, and
+their handling of buffer-local values is actually a bit more complicated
+than outlined above and even customizable.
+
+
+File: doccZhEUk.info,  Node: Using History,  Next: Getting Help for Suffix Commands,  Prev: Saving Values,  Up: Usage
+
+2.5 Using History
+=================
+
+Every time the user invokes a suffix command the transient’s current
+value is saved to its history.  These values can be cycled through, the
+same way one can cycle through the history of commands that read
+user-input in the minibuffer.
+
+Key: C-M-p (transient-history-prev)
+
+Key: C-x p
+     This command switches to the previous value used for the active
+     transient.
+
+Key: C-M-n (transient-history-next)
+
+Key: C-x n
+     This command switches to the next value used for the active
+     transient.
+
+   In addition to the transient-wide history, infixes can have their own
+history.  When an infix reads user-input using the minibuffer, the user
+can use the regular minibuffer history commands to cycle through
+previously used values.  Usually the same keys as those mentioned above
+are bound to those commands.
+
+   Authors of transients should arrange for different infix commands
+that read the same kind of value to also use the same history key (see
+*note Suffix Slots::).
+
+   Both kinds of history are saved to a file when Emacs is exited.
+
+User Option: transient-save-history
+     This option controls whether the history of transient commands is
+     saved when exiting Emacs.
+
+User Option: transient-history-file
+     This option names the file that is used to persist the history of
+     transients and their infixes between Emacs sessions.
+
+User Option: transient-history-limit
+     This option controls how many history elements are kept at the time
+     the history is saved in ‘transient-history-file’.

+
+2.6 Getting Help for Suffix Commands
+====================================
+
+Transients can have many suffixes and infixes that the user might not be
+familiar with.  To make it trivial to get help for these, Transient
+provides access to the documentation directly from the active transient.
+
+Key: C-h (transient-help)
+     This command enters help mode.  When help mode is active, typing a
+     key shows information about the suffix command that the key
+     normally is bound to (instead of invoking it).  Pressing ‘C-h’ a
+     second time shows information about the _prefix_ command.
+
+     After typing a key, the stack of transient states is suspended and
+     information about the suffix command is shown instead.  Typing ‘q’
+     in the help buffer buries that buffer and resumes the transient
+     state.
+
+   What sort of documentation is shown depends on how the transient was
+defined.  For infix commands that represent command-line arguments this
+ideally shows the appropriate manpage.  ‘transient-help’ then tries to
+jump to the correct location within that.  Info manuals are also
+supported.  The fallback is to show the command’s documentation string,
+for non-infix suffixes this is usually appropriate.
+
+

+
+2.7 Enabling and Disabling Suffixes
+===================================
+
+The user base of a package that uses transients can be very diverse.
+This is certainly the case for Magit; some users have been using it and
+Git for a decade, while others are just getting started now.
+
+   For that reason a mechanism is needed that authors can use to
+classify a transient’s infixes and suffixes along the
+essentials...everything spectrum.  We use the term “levels” to describe
+that mechanism.
+
+   Each suffix command is placed on a level and each transient has a
+level (called “transient-level”), which controls which suffix commands
+are available.  Integers between 1 and 7 (inclusive) are valid levels.
+For suffixes, 0 is also valid; it means that the suffix is not displayed
+at any level.
+
+   The levels of individual transients and/or their individual suffixes
+can be changed interactively, by invoking the transient and then
+pressing ‘C-x l’ to enter the “edit” mode, see below.
+
+   The default level for both transients and their suffixes is 4.  The
+‘transient-default-level’ option only controls the default for
+transients.  The default suffix level is always 4.  The authors of
+transients should place certain suffixes on a higher level, if they
+expect that it won’t be of use to most users, and they should place very
+important suffixes on a lower level, so that they remain available even
+if the user lowers the transient level.
+
+User Option: transient-default-level
+     This option controls which suffix levels are made available by
+     default.  It sets the transient-level for transients for which the
+     user has not set that individually.
+
+User Option: transient-levels-file
+     This option names the file that is used to persist the levels of
+     transients and their suffixes between Emacs sessions.
+
+Key: C-x l (transient-set-level)
+     This command enters edit mode.  When edit mode is active, then all
+     infixes and suffixes that are currently usable are displayed along
+     with their levels.  The colors of the levels indicate whether they
+     are enabled or not.  The level of the transient is also displayed
+     along with some usage information.
+
+     In edit mode, pressing the key that would usually invoke a certain
+     suffix instead prompts the user for the level that suffix should be
+     placed on.
+
+     Help mode is available in edit mode.
+
+     To change the transient level press ‘C-x l’ again.
+
+     To exit edit mode press ‘C-g’.
+
+     Note that edit mode does not display any suffixes that are not
+     currently usable.  ‘magit-rebase’, for example, shows different
+     suffixes depending on whether a rebase is already in progress or
+     not.  The predicates also apply in edit mode.
+
+     Therefore, to control which suffixes are available given a certain
+     state, you have to make sure that that state is currently active.
+
+Key: C-x a (transient-toggle-level-limit)
+     This command toggle whether suffixes that are on levels higher than
+     the level specified by ‘transient-default-level’ are temporarily
+     available anyway.
+
+Function: transient-set-default-level suffix level
+     This function sets the default level of the suffix COMMAND to
+     LEVEL.
+
+     If a suffix command appears in multiple menus, it may make sense to
+     consistently change its level in all those menus at once.  For
+     example, the ‘--gpg-sign’ argument (which is implemented using the
+     command ‘magit:--gpg-sign’), is bound in all of Magit’s menu which
+     create commits.  Users who sometimes sign their commits would want
+     that argument to be available in all of these menus, while for
+     users who never sign it is just unnecessary noise in any menus.
+
+     To always make ‘--gpg-sign’ available, use:
+
+          (transient-set-default-level 'magit:--gpg-sign 1)
+
+     To never make ‘--gpg-sign’ available, use:
+
+          (transient-set-default-level 'magit:--gpg-sign 0)
+
+     This sets the level in the suffix prototype object for this
+     command.  Commands only have a suffix prototype if they were
+     defined using one of ‘transient-define-argument’,
+     ‘transient-define-infix’ and ‘transient-define-suffix’.  For all
+     other commands this would signal an error.  (This is one of the
+     reasons why package authors should use one of these functions to
+     define shared suffix commands, and especially shared arguments.)
+
+     If the user changes the level of a suffix in a particular menu,
+     using ‘C-x l’ as shown above, then that obviously shadows the
+     default.
+
+     It is also possible to set the level of a suffix binding in a
+     particular menu, either when defining the menu using
+     ‘transient-define-prefix,’ or later using
+     ‘transient-insert-suffix’.  If such bindings specify a level, then
+     that also overrides the default.  (Per-suffix default levels is a
+     new feature, so you might encounter this quite often.)

+
+2.8 Other Commands
+==================
+
+When invoking a transient in a small frame, the transient window may not
+show the complete buffer, making it necessary to scroll, using the
+following commands.  These commands are never shown in the transient
+window, and the key bindings are the same as for ‘scroll-up-command’ and
+‘scroll-down-command’ in other buffers.
+
+Command: transient-scroll-up arg
+     This command scrolls text of transient popup window upward ARG
+     lines.  If ARG is ‘nil’, then it scrolls near full screen.  This is
+     a wrapper around ‘scroll-up-command’ (which see).
+
+Command: transient-scroll-down arg
+     This command scrolls text of transient popup window down ARG lines.
+     If ARG is ‘nil’, then it scrolls near full screen.  This is a
+     wrapper around ‘scroll-down-command’ (which see).
+
+   The following commands are not available by default.  If you would
+like to use them for all menus, bind them in ‘transient-map’.
+
+Command: transient-copy-menu-text
+     This command copies the contents of the menu buffer to the kill
+     ring.
+
+Command: transient-toggle-docstrings
+     This command toggle between showing suffix descriptions in the menu
+     (as usual) or showing the first lines of the respective docstrings
+     in their place.  For commands that do not have a docstring, always
+     display the suffix description.  Because there likely isn’t enough
+     room to display multiple docstrings side-by-side, a single column
+     is used when displaying docstrings.

+2.9 Configuration
+=================
+
+More options are described in *note Common Suffix Commands::, in *note
+Saving Values::, in *note Using History:: and in *note Enabling and
+Disabling Suffixes::.
+
+Essential Options
+-----------------
+
+Also see *note Common Suffix Commands::.
+
+User Option: transient-show-popup
+     This option controls whether the current transient’s infix and
+     suffix commands are shown in the popup buffer.
+
+        • If ‘t’ (the default) then the popup buffer is shown as soon as
+          a transient prefix command is invoked.
+
+        • If ‘nil’, then the popup buffer is not shown unless the user
+          explicitly requests it, by pressing an incomplete prefix key
+          sequence.
+
+        • If a number, then the a brief one-line summary is shown
+          instead of the popup buffer.  If zero or negative, then not
+          even that summary is shown; only the pressed key itself is
+          shown.
+
+          The popup is shown when the user explicitly requests it by
+          pressing an incomplete prefix key sequence.  Unless this is
+          zero, the popup is shown after that many seconds of inactivity
+          (using the absolute value).
+
+User Option: transient-show-common-commands
+     This option controls whether shared suffix commands are shown
+     alongside the transient-specific infix and suffix commands.  By
+     default, the shared commands are not shown to avoid overwhelming
+     the user with too many options.
+
+     While a transient is active, pressing ‘C-x’ always shows the common
+     commands.  The value of this option can be changed for the current
+     Emacs session by typing ‘C-x t’ while a transient is active.
+
+User Option: transient-show-during-minibuffer-read
+     This option controls whether the transient menu continues to be
+     displayed while the minibuffer is used to read user input.
+
+     This is only relevant to commands that do not close the menu, such
+     as commands that set infix arguments.  If a command exits the menu,
+     and uses the minibuffer, then the menu is always closed before the
+     minibuffer is entered, irrespective of the value of this option.
+
+     When ‘nil’ (the default), hide the menu while the minibuffer is in
+     use.  When ‘t’, keep showing the menu, but allow for the menu
+     window to be resized, to ensure that completion candidates can be
+     displayed.
+
+     When ‘fixed’, keep showing the menu and prevent it from being
+     resized, which may make it impossible to display the completion
+     candidates.  If that ever happens for you, consider using ‘t’ or an
+     integer, as described below.
+
+     If the value is ‘fixed’ and the menu window uses the full height of
+     its frame, then the former is ignored and resizing is allowed
+     anyway.  This is necessary because individual menus may use unusual
+     display actions different from what
+     ‘transient-display-buffer-action’ specifies (likely to display that
+     menu in a side-window).
+
+     When using a third-party mode, which automatically resizes windows
+     (e.g., by calling ‘balance-windows’ on ‘post-command-hook’), then
+     ‘fixed’ (or ‘nil’) is likely a better choice than ‘t’.
+
+     The value can also be an integer, in which case the behavior
+     depends on whether at least that many lines are left to display
+     windows other than the menu window.  If that is the case, display
+     the menu and preserve the size of that window.  Otherwise, allow
+     resizing the menu window if the number is positive, or hide the
+     menu if it is negative.
+
+User Option: transient-read-with-initial-input
+     This option controls whether the last history element is used as
+     the initial minibuffer input when reading the value of an infix
+     argument from the user.  If ‘nil’, there is no initial input and
+     the first element has to be accessed the same way as the older
+     elements.
+
+User Option: transient-enable-popup-navigation
+     This option controls whether navigation commands are enabled in the
+     transient popup buffer.  If the value is ‘verbose’ (the default),
+     brief documentation about the command under point is additionally
+     show in the echo area.
+
+     While a transient is active the transient popup buffer is not the
+     current buffer, making it necessary to use dedicated commands to
+     act on that buffer itself.  If this option is non-‘nil’, then the
+     following features are available:
+
+        • ‘<UP>’ moves the cursor to the previous suffix.
+        • ‘<DOWN>’ moves the cursor to the next suffix.
+        • ‘M-<RET>’ invokes the suffix the cursor is on.
+        • ‘mouse-1’ invokes the clicked on suffix.
+        • ‘C-s’ and ‘C-r’ start isearch in the popup buffer.
+
+     By default ‘M-<RET>’ is bound to ‘transient-push-button’, instead
+     of ‘<RET>’, because if a transient allows the invocation of
+     non-suffixes, then it is likely, that you would want ‘<RET>’ to do
+     what it would do if no transient were active."
+
+User Option: transient-display-buffer-action
+     This option specifies the action used to display the transient
+     popup buffer.  The transient popup buffer is displayed in a window
+     using ‘(display-buffer BUFFER transient-display-buffer-action)’.
+
+     The value of this option has the form ‘(FUNCTION . ALIST)’, where
+     FUNCTION is a function or a list of functions.  Each such function
+     should accept two arguments: a buffer to display and an alist of
+     the same form as ALIST.  See *note (elisp)Choosing Window::, for
+     details.
+
+     The default is:
+
+          (display-buffer-in-side-window
+           (side . bottom)
+           (dedicated . t)
+           (inhibit-same-window . t))
+
+     This displays the window at the bottom of the selected frame.  For
+     alternatives see *note (elisp)Buffer Display Action Functions::,
+     and *note (elisp)Buffer Display Action Alists::.
+
+     When you switch to a different ACTION, you should keep the ALIST
+     entries for ‘dedicated’ and ‘inhibit-same-window’ in most cases.
+     Do not drop them because you are unsure whether they are needed; if
+     you are unsure, then keep them.
+
+     Note that the buffer that was current before the transient buffer
+     is shown should remain the current buffer.  Many suffix commands
+     act on the thing at point, if appropriate, and if the transient
+     buffer became the current buffer, then that would change what is at
+     point.  To that effect ‘inhibit-same-window’ ensures that the
+     selected window is not used to show the transient buffer.
+
+     It may be possible to display the window in another frame, but
+     whether that works in practice depends on the window-manager.  If
+     the window manager selects the new window (Emacs frame), then that
+     unfortunately changes which buffer is current.
+
+     If you change the value of this option, then you might also want to
+     change the value of ‘transient-mode-line-format’.
+
+     This user option may be overridden if ‘:display-action’ is passed
+     when creating a new prefix with ‘transient-define-prefix’.
+
+Accessibility Options
+---------------------
+
+User Option: transient-force-single-column
+     This option controls whether the use of a single column to display
+     suffixes is enforced.  This might be useful for users with low
+     vision who use large text and might otherwise have to scroll in two
+     dimensions.
+
+Auxiliary Options
+-----------------
+
+User Option: transient-mode-line-format
+     This option controls whether the transient popup buffer has a
+     mode-line, separator line, or neither.
+
+     If ‘nil’, then the buffer has no mode-line.  If the buffer is not
+     displayed right above the echo area, then this probably is not a
+     good value.
+
+     If ‘line’ (the default) or a natural number, then the buffer has no
+     mode-line, but a line is drawn in its place.  If a number is used,
+     that specifies the thickness of the line.  On termcap frames we
+     cannot draw lines, so there ‘line’ and numbers are synonyms for
+     ‘nil’.
+
+     The color of the line is used to indicate if non-suffixes are
+     allowed and whether they exit the transient.  The foreground color
+     of ‘transient-key-noop’ (if non-suffixes are disallowed),
+     ‘transient-key-stay’ (if allowed and transient stays active), or
+     ‘transient-key-exit’ (if allowed and they exit the transient) is
+     used to draw the line.
+
+     This user option may be overridden if ‘:mode-line-format’ is passed
+     when creating a new prefix with ‘transient-define-prefix’.
+
+     Otherwise this can be any mode-line format.  See *note (elisp)Mode
+     Line Format::, for details.
+
+User Option: transient-semantic-coloring
+     This option controls whether colors are used to indicate the
+     transient behavior of commands.
+
+     If non-‘nil’, then the key binding of each suffix is colorized to
+     indicate whether it exits the transient state or not.  The color of
+     the prefix is indicated using the line that is drawn when the value
+     of ‘transient-mode-line-format’ is ‘line’.
+
+User Option: transient-highlight-mismatched-keys
+     This option controls whether key bindings of infix commands that do
+     not match the respective command-line argument should be
+     highlighted.  For other infix commands this option has no effect.
+
+     When this option is non-‘nil’, the key binding for an infix
+     argument is highlighted when only a long argument (e.g.,
+     ‘--verbose’) is specified but no shorthand (e.g., ‘-v’).  In the
+     rare case that a shorthand is specified but the key binding does
+     not match, then it is highlighted differently.
+
+     Highlighting mismatched key bindings is useful when learning the
+     arguments of the underlying command-line tool; you wouldn’t want to
+     learn any short-hands that do not actually exist.
+
+     The highlighting is done using one of the faces
+     ‘transient-mismatched-key’ and ‘transient-nonstandard-key’.
+
+User Option: transient-substitute-key-function
+     This function is used to modify key bindings.  If the value of this
+     option is ‘nil’ (the default), then no substitution is performed.
+
+     This function is called with one argument, the prefix object, and
+     must return a key binding description, either the existing key
+     description it finds in the ‘key’ slot, or the key description that
+     replaces the prefix key.  It could be used to make other
+     substitutions, but that is discouraged.
+
+     For example, ‘=’ is hard to reach using my custom keyboard layout,
+     so I substitute ‘(’ for that, which is easy to reach using a layout
+     optimized for lisp.
+
+          (setq transient-substitute-key-function
+                (lambda (obj)
+                  (let ((key (oref obj key)))
+                    (if (string-match "\\`\\(=\\)[a-zA-Z]" key)
+                        (replace-match "(" t t key 1)
+                      key))))
+
+User Option: transient-align-variable-pitch
+     This option controls whether columns are aligned pixel-wise in the
+     popup buffer.
+
+     If this is non-‘nil’, then columns are aligned pixel-wise to
+     support variable-pitch fonts.  Keys are not aligned, so you should
+     use a fixed-pitch font for the ‘transient-key’ face.  Other key
+     faces inherit from that face unless a theme is used that breaks
+     that relationship.
+
+     This option is intended for users who use a variable-pitch font for
+     the ‘default’ face.
+
+User Option: transient-force-fixed-pitch
+     This option controls whether to force the use of a monospaced font
+     in popup buffer.  Even if you use a proportional font for the
+     ‘default’ face, you might still want to use a monospaced font in
+     transient’s popup buffer.  Setting this option to ‘t’ causes
+     ‘default’ to be remapped to ‘fixed-pitch’ in that buffer.
+
+Developer Options
+-----------------
+
+These options are mainly intended for developers.
+
+User Option: transient-detect-key-conflicts
+     This option controls whether key binding conflicts should be
+     detected at the time the transient is invoked.  If so, this results
+     in an error, which prevents the transient from being used.  Because
+     of that, conflicts are ignored by default.
+
+     Conflicts cannot be determined earlier, i.e., when the transient is
+     being defined and when new suffixes are being added, because at
+     that time there can be false-positives.  It is actually valid for
+     multiple suffixes to share a common key binding, provided the
+     predicates of those suffixes prevent that more than one of them is
+     enabled at a time.
+
+User Option: transient-highlight-higher-levels
+     This option controls whether suffixes that would not be available
+     by default are highlighted.
+
+     When non-‘nil’ then the descriptions of suffixes are highlighted if
+     their level is above 4, the default of ‘transient-default-level’.
+     Assuming you have set that variable to 7, this highlights all
+     suffixes that won’t be available to users without them making the
+     same customization.
+
+Hook Variables
+--------------
+
+Variable: transient-exit-hook
+     This hook is run after a transient is exited.
+
+Variable: transient-setup-buffer-hook
+     This hook is run when the transient buffer is being setup.  That
+     buffer is current and empty when this hook is runs.

+
+3 Modifying Existing Transients
+*******************************
+
+To an extent, transients can be customized interactively, see *note
+Enabling and Disabling Suffixes::.  This section explains how existing
+transients can be further modified non-interactively.  Let’s begin with
+an example:
+
+     (transient-append-suffix 'magit-patch-apply "-3"
+       '("-R" "Apply in reverse" "--reverse"))
+
+   This inserts a new infix argument to toggle the ‘--reverse’ argument
+after the infix argument that toggles ‘-3’ in ‘magit-patch-apply’.
+
+   The following functions share a few arguments:
+
+   • PREFIX is a transient prefix command, a symbol.
+
+   • SUFFIX is a transient infix or suffix specification in the same
+     form as expected by ‘transient-define-prefix’.  Note that an infix
+     is a special kind of suffix.  Depending on context “suffixes” means
+     “suffixes (including infixes)” or “non-infix suffixes”.  Here it
+     means the former.  See *note Suffix Specifications::.
+
+     SUFFIX may also be a group in the same form as expected by
+     ‘transient-define-prefix’.  See *note Group Specifications::.
+
+   • LOC is a command, a key vector, a key description (a string as
+     returned by ‘key-description’), or a list specifying coordinates
+     (the last element may also be a command or key).  For example ‘(1 0
+     -1)’ identifies the last suffix (‘-1’) of the first subgroup (‘0’)
+     of the second group (‘1’).
+
+     If LOC is a list of coordinates, then it can be used to identify a
+     group, not just an individual suffix command.
+
+     The function ‘transient-get-suffix’ can be useful to determine
+     whether a certain coordination list identifies the suffix or group
+     that you expect it to identify.  In hairy cases it may be necessary
+     to look at the definition of the transient prefix command.
+
+   These functions operate on the information stored in the
+‘transient--layout’ property of the PREFIX symbol.  Suffix entries in
+that tree are not objects but have the form ‘(LEVEL CLASS PLIST)’, where
+PLIST should set at least ‘:key’, ‘:description’ and ‘:command’.
+
+Function: transient-insert-suffix prefix loc suffix &optional keep-other
+
+Function: transient-append-suffix prefix loc suffix &optional keep-other
+     These functions insert the suffix or group SUFFIX into PREFIX
+     before or after LOC.
+
+     Conceptually adding a binding to a transient prefix is similar to
+     adding a binding to a keymap, but this is complicated by the fact
+     that multiple suffix commands can be bound to the same key,
+     provided they are never active at the same time, see *note
+     Predicate Slots::.
+
+     Unfortunately both false-positives and false-negatives are
+     possible.  To deal with the former use non-‘nil’ KEEP-OTHER.  The
+     symbol ‘always’ prevents the removal of a false-positive in some
+     cases where other non-‘nil’ values would fail.  To deal with
+     false-negatives remove the conflicting binding separately, using
+     ‘transient-remove-suffix’.
+
+Function: transient-replace-suffix prefix loc suffix
+     This function replaces the suffix or group at LOC in PREFIX with
+     suffix or group SUFFIX.
+
+Function: transient-remove-suffix prefix loc
+     This function removes the suffix or group at LOC in PREFIX.
+
+Function: transient-get-suffix prefix loc
+     This function returns the suffix or group at LOC in PREFIX.  The
+     returned value has the form mentioned above.
+
+Function: transient-suffix-put prefix loc prop value
+     This function edits the suffix or group at LOC in PREFIX, by
+     setting the PROP of its plist to VALUE.
+
+   Most of these functions do not signal an error if they cannot perform
+the requested modification.  The functions that insert new suffixes show
+a warning if LOC cannot be found in PREFIX without signaling an error.
+The reason for doing it like this is that establishing a key binding
+(and that is what we essentially are trying to do here) should not
+prevent the rest of the configuration from loading.  Among these
+functions only ‘transient-get-suffix’ and ‘transient-suffix-put’ may
+signal an error.

+
+4.1 Technical Introduction
+==========================
+
+Taking inspiration from prefix keys and prefix arguments, Transient
+implements a similar abstraction involving a prefix command, infix
+arguments and suffix commands.
+
+   When the user calls a transient prefix command, a transient
+(temporary) keymap is activated, which binds the transient’s infix and
+suffix commands, and functions that control the transient state are
+added to ‘pre-command-hook’ and ‘post-command-hook’.  The available
+suffix and infix commands and their state are shown in a popup buffer
+until the transient state is exited by invoking a suffix command.
+
+   Calling an infix command causes its value to be changed.  How that is
+done depends on the type of the infix command.  The simplest case is an
+infix command that represents a command-line argument that does not take
+a value.  Invoking such an infix command causes the switch to be toggled
+on or off.  More complex infix commands may read a value from the user,
+using the minibuffer.
+
+   Calling a suffix command usually causes the transient to be exited;
+the transient keymaps and hook functions are removed, the popup buffer
+no longer shows information about the (no longer bound) suffix commands,
+the values of some public global variables are set, while some internal
+global variables are unset, and finally the command is actually called.
+Suffix commands can also be configured to not exit the transient.
+
+   A suffix command can, but does not have to, use the infix arguments
+in much the same way any command can choose to use or ignore the prefix
+arguments.  For a suffix command that was invoked from a transient, the
+variable ‘transient-current-suffixes’ and the function ‘transient-args’
+serve about the same purpose as the variables ‘prefix-arg’ and
+‘current-prefix-arg’ do for any command that was called after the prefix
+arguments have been set using a command such as ‘universal-argument’.
+
+   Transient can be used to implement simple “command dispatchers”.  The
+main benefit then is that the user can see all the available commands in
+a popup buffer, which can be thought of as a “menu”.  That is useful by
+itself because it frees the user from having to remember all the keys
+that are valid after a certain prefix key or command.  Magit’s
+‘magit-dispatch’ (on ‘C-x M-g’) command is an example of using Transient
+to merely implement a command dispatcher.
+
+   In addition to that, Transient also allows users to interactively
+pass arguments to commands.  These arguments can be much more complex
+than what is reasonable when using prefix arguments.  There is a limit
+to how many aspects of a command can be controlled using prefix
+arguments.  Furthermore, what a certain prefix argument means for
+different commands can be completely different, and users have to read
+documentation to learn and then commit to memory what a certain prefix
+argument means to a certain command.
+
+   Transient suffix commands, on the other hand, can accept dozens of
+different arguments without the user having to remember anything.  When
+using Transient, one can call a command with arguments that are just as
+complex as when calling the same function non-interactively from Lisp.
+
+   Invoking a transient suffix command with arguments is similar to
+invoking a command in a shell with command-line completion and history
+enabled.  One benefit of the Transient interface is that it remembers
+history not only on a global level (“this command was invoked using
+these arguments, and previously it was invoked using those other
+arguments”), but also remembers the values of individual arguments
+independently.  See *note Using History::.
+
+   After a transient prefix command is invoked, ‘C-h KEY’ can be used to
+show the documentation for the infix or suffix command that ‘KEY’ is
+bound to (see *note Getting Help for Suffix Commands::), and infixes and
+suffixes can be removed from the transient using ‘C-x l KEY’.  Infixes
+and suffixes that are disabled by default can be enabled the same way.
+See *note Enabling and Disabling Suffixes::.
+
+   Transient ships with support for a few different types of specialized
+infix commands.  A command that sets a command line option, for example,
+has different needs than a command that merely toggles a boolean flag.
+Additionally, Transient provides abstractions for defining new types,
+which the author of Transient did not anticipate (or didn’t get around
+to implementing yet).
+
+   Note that suffix commands also support regular prefix arguments.  A
+suffix command may even be called with both infix and prefix arguments
+at the same time.  If you invoke a command as a suffix of a transient
+prefix command, but also want to pass prefix arguments to it, then first
+invoke the prefix command, and only after doing that invoke the prefix
+arguments, before finally invoking the suffix command.  If you instead
+began by providing the prefix arguments, then those would apply to the
+prefix command, not the suffix command.  Likewise, if you want to change
+infix arguments before invoking a suffix command with prefix arguments,
+then change the infix arguments before invoking the prefix arguments.
+In other words, regular prefix arguments always apply to the next
+command, and since transient prefix, infix and suffix commands are just
+regular commands, the same applies to them.  (Regular prefix keys behave
+differently because they are not commands at all, instead they are just
+incomplete key sequences, and those cannot be interrupted with prefix
+commands.)

+
+4.2 Defining Transients
+=======================
+
+A transient consists of a prefix command and at least one suffix
+command, though usually a transient has several infix and suffix
+commands.  The below macro defines the transient prefix command *and*
+binds the transient’s infix and suffix commands.  In other words, it
+defines the complete transient, not just the transient prefix command
+that is used to invoke that transient.
+
+Macro: transient-define-prefix name arglist [docstring] [keyword value]... group... [body...]
+     This macro defines NAME as a transient prefix command and binds the
+     transient’s infix and suffix commands.
+
+     ARGLIST are the arguments that the prefix command takes.  DOCSTRING
+     is the documentation string and is optional.
+
+     These arguments can optionally be followed by keyword-value pairs.
+     Each key has to be a keyword symbol, either ‘:class’ or a keyword
+     argument supported by the constructor of that class.  The
+     ‘transient-prefix’ class is used if the class is not specified
+     explicitly.
+
+     GROUPs add key bindings for infix and suffix commands and specify
+     how these bindings are presented in the popup buffer.  At least one
+     GROUP has to be specified.  See *note Binding Suffix and Infix
+     Commands::.
+
+     The BODY is optional.  If it is omitted, then ARGLIST is ignored
+     and the function definition becomes:
+
+          (lambda ()
+            (interactive)
+            (transient-setup 'NAME))
+
+     If BODY is specified, then it must begin with an ‘interactive’ form
+     that matches ARGLIST, and it must call ‘transient-setup’.  It may,
+     however, call that function only when some condition is satisfied.
+
+     All transients have a (possibly ‘nil’) value, which is exported
+     when suffix commands are called, so that they can consume that
+     value.  For some transients it might be necessary to have a sort of
+     secondary value, called a “scope”.  Such a scope would usually be
+     set in the command’s ‘interactive’ form and has to be passed to the
+     setup function:
+
+          (transient-setup 'NAME nil nil :scope SCOPE)
+
+     For example, the scope of the ‘magit-branch-configure’ transient is
+     the branch whose variables are being configured.

+
+4.3 Binding Suffix and Infix Commands
+=====================================
+
+The macro ‘transient-define-prefix’ is used to define a transient.  This
+defines the actual transient prefix command (see *note Defining
+Transients::) and adds the transient’s infix and suffix bindings, as
+described below.
+
+   Users and third-party packages can add additional bindings using
+functions such as ‘transient-insert-suffix’ (see *note Modifying
+Existing Transients::).  These functions take a “suffix specification”
+as one of their arguments, which has the same form as the specifications
+used in ‘transient-define-prefix’.
+
+* Menu:
+
+* Group Specifications::
+* Suffix Specifications::
+
+
+File: doccZhEUk.info,  Node: Group Specifications,  Next: Suffix Specifications,  Up: Binding Suffix and Infix Commands
+
+4.3.1 Group Specifications
+--------------------------
+
+The suffix and infix commands of a transient are organized in groups.
+The grouping controls how the descriptions of the suffixes are outlined
+visually but also makes it possible to set certain properties for a set
+of suffixes.
+
+   Several group classes exist, some of which organize suffixes in
+subgroups.  In most cases the class does not have to be specified
+explicitly, but see *note Group Classes::.
+
+   Groups are specified in the call to ‘transient-define-prefix’, using
+vectors.  Because groups are represented using vectors, we cannot use
+square brackets to indicate an optional element and instead use curly
+brackets to do the latter.
+
+   Group specifications then have this form:
+
+     [{LEVEL} {DESCRIPTION} {KEYWORD VALUE}... ELEMENT...]
+
+   The LEVEL is optional and defaults to 4.  See *note Enabling and
+Disabling Suffixes::.
+
+   The DESCRIPTION is optional.  If present, it is used as the heading
+of the group.
+
+   The KEYWORD-VALUE pairs are optional.  Each keyword has to be a
+keyword symbol, either ‘:class’ or a keyword argument supported by the
+constructor of that class.
+
+   • One of these keywords, ‘:description’, is equivalent to specifying
+     DESCRIPTION at the very beginning of the vector.  The
+     recommendation is to use ‘:description’ if some other keyword is
+     also used, for consistency, or DESCRIPTION otherwise, because it
+     looks better.
+
+   • Likewise ‘:level’ is equivalent to LEVEL.
+
+   • Other important keywords include the ‘:if...’ and ‘:inapt-if...’
+     keywords.  These keywords control whether the group is available in
+     a certain situation.
+
+     For example, one group of the ‘magit-rebase’ transient uses ‘:if
+     magit-rebase-in-progress-p’, which contains the suffixes that are
+     useful while rebase is already in progress; and another that uses
+     ‘:if-not magit-rebase-in-progress-p’, which contains the suffixes
+     that initiate a rebase.
+
+     These predicates can also be used on individual suffixes and are
+     only documented once, see *note Predicate Slots::.
+
+   • The value of ‘:hide’, if non-‘nil’, is a predicate that controls
+     whether the group is hidden by default.  The key bindings for
+     suffixes of a hidden group should all use the same prefix key.
+     Pressing that prefix key should temporarily show the group and its
+     suffixes, which assumes that a predicate like this is used:
+
+          (lambda ()
+            (eq (car transient--redisplay-key)
+                ?\C-c)) ; the prefix key shared by all bindings
+
+   • The value of ‘:setup-children’, if non-‘nil’, is a function that
+     takes one argument, a potentially list of children, and must return
+     a list of children or an empty list.  This can either be used to
+     somehow transform the group’s children that were defined the normal
+     way, or to dynamically create the children from scratch.
+
+     The returned children must have the same form as stored in the
+     prefix’s ‘transient--layout’ property, but it is often more
+     convenient to use the same form as understood by
+     ‘transient-define-prefix’, described below.  If you use the latter
+     approach, you can use the ‘transient-parse-suffixes’ and
+     ‘transient-parse-suffix’ functions to transform them from the
+     convenient to the expected form.  Depending on the used group
+     class, ‘transient-parse-suffixes’’s SUFFIXES must be a list of
+     group vectors (for ‘transient-columns’) or a list of suffix lists
+     (for all other group classes).
+
+     If you explicitly specify children and then transform them using
+     ‘:setup-children’, then the class of the group is determined as
+     usual, based on explicitly specified children.
+
+     If you do not explicitly specify children and thus rely solely on
+     ‘:setup-children’, then you must specify the class using ‘:class’.
+     For backward compatibility, if you fail to do so,
+     ‘transient-column’ is used and a warning is displayed.  This
+     warning will eventually be replaced with an error.
+
+          (transient-define-prefix my-finder-by-keyword ()
+            "Select a keyword and list matching packages."
+            ;; The real `finder-by-keyword' is more convenient
+            ;; of course, but that is not the point here.
+            [:class transient-columns
+             :setup-children
+             (lambda (_)
+               (transient-parse-suffixes
+                'my-finder-by-keyword
+                (let ((char (1- ?A)))
+                  (mapcar                  ; a list ...
+                   (lambda (partition)
+                     (vconcat              ; of group vectors ...
+                      (mapcar (lambda (elt)
+                                (let ((keyword (symbol-name (car elt))))
+                                           ; ... where each suffix is a list
+                                  (list (format "%c" (cl-incf char))
+                                        keyword
+                                        (lambda ()
+                                          (interactive)
+                                          (finder-list-matches keyword)))))
+                              partition)))
+                   (seq-partition finder-known-keywords 7)))))])
+
+   • The boolean ‘:pad-keys’ argument controls whether keys of all
+     suffixes contained in a group are right padded, effectively
+     aligning the descriptions.
+
+   • If a keyword argument accepts a function as value, you an use a
+     ‘lambda’ expression.  As a special case, the ‘##’ macro (which
+     returns a ‘lambda’ expression and is implemented in the ‘llama’
+     package) is also supported.  Inside group specifications, the use
+     of ‘##’ is not supported anywhere but directly following a keyword
+     symbol.
+
+   The ELEMENTs are either all subgroups, or all suffixes and strings.
+(At least currently no group type exists that would allow mixing
+subgroups with commands at the same level, though in principle there is
+nothing that prevents that.)
+
+   If the ELEMENTs are not subgroups, then they can be a mixture of
+lists, which specify commands, and strings.  Strings are inserted
+verbatim into the buffer.  The empty string can be used to insert gaps
+between suffixes, which is particularly useful if the suffixes are
+outlined as a table.
+
+   Inside group specifications, including inside contained suffix
+specifications, nothing has to be quoted and quoting anyway is invalid.
+The value following a keyword, can be explicitly unquoted using ‘,’.
+This feature is experimental and should be avoided.
+
+   The form of suffix specifications is documented in the next node.
+
+
+File: doccZhEUk.info,  Node: Suffix Specifications,  Prev: Group Specifications,  Up: Binding Suffix and Infix Commands
+
+4.3.2 Suffix Specifications
+---------------------------
+
+A transient’s suffix and infix commands are bound when the transient
+prefix command is defined using ‘transient-define-prefix’, see *note
+Defining Transients::.  The commands are organized into groups, see
+*note Group Specifications::.  Here we describe the form used to bind an
+individual suffix command.
+
+   The same form is also used when later binding additional commands
+using functions such as ‘transient-insert-suffix’, see *note Modifying
+Existing Transients::.
+
+   Note that an infix is a special kind of suffix.  Depending on context
+“suffixes” means “suffixes (including infixes)” or “non-infix suffixes”.
+Here it means the former.
+
+   Suffix specifications have this form:
+
+     ([LEVEL] [KEY [DESCRIPTION]] COMMAND|ARGUMENT [KEYWORD VALUE]...)
+
+   LEVEL, KEY and DESCRIPTION can also be specified using the KEYWORDs
+‘:level’, ‘:key’ and ‘:description’.  If the object that is associated
+with COMMAND sets these properties, then they do not have to be
+specified here.  You can however specify them here anyway, possibly
+overriding the object’s values just for the binding inside this
+transient.
+
+   • LEVEL is the suffix level, an integer between 1 and 7.  See *note
+     Enabling and Disabling Suffixes::.
+
+   • KEY is the key binding, either a vector or key description string.
+
+   • DESCRIPTION is the description, either a string or a function that
+     takes zero or one arguments (the suffix object) and returns a
+     string.  The function should be a lambda expression to avoid
+     ambiguity.  In some cases a symbol that is bound as a function
+     would also work but to be safe you should use ‘:description’ in
+     that case.
+
+   The next element is either a command or an argument.  This is the
+only argument that is mandatory in all cases.
+
+   • COMMAND should be a symbol that is bound as a function, which has
+     to be defined or at least autoloaded as a command by the time the
+     containing prefix command is invoked.
+
+     Any command will do; it does not need to have an object associated
+     with it (as would be the case if ‘transient-define-suffix’ or
+     ‘transient-define-infix’ were used to define it).
+
+     COMMAND can also be a ‘lambda’ expression.
+
+     As mentioned above, the object that is associated with a command
+     can be used to set the default for certain values that otherwise
+     have to be set in the suffix specification.  Therefore if there is
+     no object, then you have to make sure to specify the KEY and the
+     DESCRIPTION.
+
+     As a special case, if you want to add a command that might be
+     neither defined nor autoloaded, you can use a workaround like:
+
+          (transient-insert-suffix 'some-prefix "k"
+            '("!" "Ceci n'est pas une commande" no-command
+              :if (lambda () (featurep 'no-library))))
+
+     Instead of ‘featurep’ you could also use ‘require’ with a non-‘nil’
+     value for NOERROR.
+
+   • The mandatory argument can also be a command-line argument, a
+     string.  In that case an anonymous command is defined and bound.
+
+     Instead of a string, this can also be a list of two strings, in
+     which case the first string is used as the short argument (which
+     can also be specified using ‘:shortarg’) and the second as the long
+     argument (which can also be specified using ‘:argument’).
+
+     Only the long argument is displayed in the popup buffer.  See
+     ‘transient-detect-key-conflicts’ for how the short argument may be
+     used.
+
+     Unless the class is specified explicitly, the appropriate class is
+     guessed based on the long argument.  If the argument ends with ‘=’
+     (e.g., ‘--format=’) then ‘transient-option’ is used, otherwise
+     ‘transient-switch’.
+
+   Finally, details can be specified using optional KEYWORD-VALUE pairs.
+Each keyword has to be a keyword symbol, either ‘:class’ or a keyword
+argument supported by the constructor of that class.  See *note Suffix
+Slots::.
+
+   If a keyword argument accepts a function as value, you an use a
+‘lambda’ expression.  As a special case, the ‘##’ macro (which returns a
+‘lambda’ expression and is implemented in the ‘llama’ package) is also
+supported.  Inside suffix bindings, the use of ‘##’ is not supported
+anywhere but directly following a keyword symbol.

+
+4.4 Defining Suffix and Infix Commands
+======================================
+
+Note that an infix is a special kind of suffix.  Depending on context
+“suffixes” means “suffixes (including infixes)” or “non-infix suffixes”.
+
+Macro: transient-define-suffix name arglist [docstring] [keyword value]... body...
+     This macro defines NAME as a transient suffix command.
+
+     ARGLIST are the arguments that the command takes.  DOCSTRING is the
+     documentation string and is optional.
+
+     These arguments can optionally be followed by keyword-value pairs.
+     Each keyword has to be a keyword symbol, either ‘:class’ or a
+     keyword argument supported by the constructor of that class.  The
+     ‘transient-suffix’ class is used if the class is not specified
+     explicitly.
+
+     The BODY must begin with an ‘interactive’ form that matches
+     ARGLIST.  The infix arguments are usually accessed by using
+     ‘transient-args’ inside ‘interactive’.
+
+Macro: transient-define-infix name arglist [docstring] [keyword value]...
+     This macro defines NAME as a transient infix command.
+
+     ARGLIST is always ignored (but mandatory never-the-less) and
+     reserved for future use.  DOCSTRING is the documentation string and
+     is optional.
+
+     At least one key-value pair is required.  All transient infix
+     commands are ‘equal’ to each other (but not ‘eq’).  It is
+     meaningless to define an infix command, without providing at least
+     one keyword argument (usually ‘:argument’ or ‘:variable’, depending
+     on the class).  The suffix class defaults to ‘transient-switch’ and
+     can be set using the ‘:class’ keyword.
+
+     The function definition is always:
+
+          (lambda ()
+            (interactive)
+            (let ((obj (transient-suffix-object)))
+              (transient-infix-set obj (transient-infix-read obj)))
+            (transient--show))
+
+     ‘transient-infix-read’ and ‘transient-infix-set’ are generic
+     functions.  Different infix commands behave differently because the
+     concrete methods are different for different infix command classes.
+     In rare cases the above command function might not be suitable,
+     even if you define your own infix command class.  In that case you
+     have to use ‘transient-define-suffix’ to define the infix command
+     and use ‘t’ as the value of the ‘:transient’ keyword.
+
+Macro: transient-define-argument name arglist [docstring] [keyword value]...
+     This macro defines NAME as a transient infix command.
+
+     This is an alias for ‘transient-define-infix’.  Only use this alias
+     to define an infix command that actually sets an infix argument.
+     To define an infix command that, for example, sets a variable, use
+     ‘transient-define-infix’ instead.

+
+4.5 Using Infix Arguments
+=========================
+
+The functions and the variables described below allow suffix commands to
+access the value of the transient from which they were invoked; which is
+the value of its infix arguments.  These variables are set when the user
+invokes a suffix command that exits the transient, but before actually
+calling the command.
+
+   When returning to the command-loop after calling the suffix command,
+the arguments are reset to ‘nil’ (which causes the function to return
+‘nil’ too).
+
+   Like for Emacs’s prefix arguments, it is advisable, but not
+mandatory, to access the infix arguments inside the command’s
+‘interactive’ form.  The preferred way of doing that is to call the
+‘transient-args’ function, which for infix arguments serves about the
+same purpose as ‘prefix-arg’ serves for prefix arguments.
+
+Function: transient-args prefix
+     This function returns the value of the transient prefix command
+     PREFIX.
+
+     If the current command was invoked from the transient prefix
+     command PREFIX, then it returns the active infix arguments.  If the
+     current command was not invoked from PREFIX, then it returns the
+     set, saved or default value for PREFIX.
+
+Function: transient-get-value
+     This function returns the value of the current prefix.
+
+     This is mostly intended for internal use, but may also be of use in
+     ‘transient-set-value’ and ‘transient-save-value’ methods.  Unlike
+     ‘transient-args’, this does not include the values of suffixes
+     whose ‘unsavable’ slot is non-‘nil’.
+
+Function: transient-arg-value arg args
+     This function returns the value of ARG as it appears in ARGS.
+
+     For a switch a boolean is returned.  For an option the value is
+     returned as a string, using the empty string for the empty value,
+     or ‘nil’ if the option does not appear in ARGS.
+
+Function: transient-suffixes prefix
+     This function returns the suffixes of the transient prefix command
+     PREFIX.  This is a list of objects.  This function should only be
+     used if you need the objects (as opposed to just their values) and
+     if the current command is not being invoked from PREFIX.
+

+
+4.6 Using Prefix Scope
+======================
+
+Some transients have a sort of secondary value, called a scope.  A
+prefix’s scope can be accessed using ‘transient-scope’; similar to how
+its value can be accessed using ‘transient-args’.
+
+Function: transient-scope prefixes classes
+     This function returns the scope of the active or current transient
+     prefix command.
+
+     If optional PREFIXES and CLASSES are both nil, return the scope of
+     the prefix currently being setup, making this variation useful,
+     e.g., in ‘:if*’ predicates.  If no prefix is being setup, but the
+     current command was invoked from some prefix, then return the scope
+     of that.
+
+     If PREFIXES is non-nil, it must be a prefix command or a list of
+     such commands.  If CLASSES is non-nil, it must be a prefix class or
+     a list of such classes.  When this function is called from the body
+     or the ‘interactive’ form of a suffix command, PREFIXES and/or
+     CLASSES should be non-nil.  If either is non-nil, try the following
+     in order:
+
+        • If the current suffix command was invoked from a prefix, which
+          appears in PREFIXES, return the scope of that prefix.
+
+        • If the current suffix command was invoked from a prefix, and
+          its class derives from one of the CLASSES, return the scope of
+          that prefix.
+
+        • If a prefix is being setup and it appears in PREFIXES, return
+          its scope.
+
+        • If a prefix is being setup and its class derives from one of
+          the CLASSES, return its scope.
+
+        • Finally try to return the default scope of the first command
+          in PREFIXES.  This only works if that slot is set in the
+          respective class definition or using its
+          ‘transient-init-scope’ method.
+
+     If no prefix matches, return nil.

+
+4.7 Current Suffix Command
+==========================
+
+Function: transient-suffix-object command
+     This function returns the object associated with the current suffix
+     command.
+
+     Each suffix commands is associated with an object, which holds
+     additional information about the suffix, such as its value (in the
+     case of an infix command, which is a kind of suffix command).
+
+     This function is intended to be called by infix commands, which are
+     usually aliases of ‘transient--default-infix-command’, which is
+     defined like this:
+
+          (defun transient--default-infix-command ()
+            (interactive)
+            (let ((obj (transient-suffix-object)))
+              (transient-infix-set obj (transient-infix-read obj)))
+            (transient--show))
+
+     (User input is read outside of ‘interactive’ to prevent the command
+     from being added to ‘command-history’.)
+
+     Such commands need to be able to access their associated object to
+     guide how ‘transient-infix-read’ reads the new value and to store
+     the read value.  Other suffix commands (including non-infix
+     commands) may also need the object to guide their behavior.
+
+     This function attempts to return the object associated with the
+     current suffix command even if the suffix command was not invoked
+     from a transient.  (For some suffix command that is a valid thing
+     to do, for others it is not.)  In that case ‘nil’ may be returned,
+     if the command was not defined using one of the macros intended to
+     define such commands.
+
+     The optional argument COMMAND is intended for internal use.  If you
+     are contemplating using it in your own code, then you should
+     probably use this instead:
+
+          (get COMMAND 'transient--suffix)
+
+Variable: transient-current-suffixes
+     The suffixes of the transient from which this suffix command was
+     invoked.  This is a list of objects.  Usually it is sufficient to
+     instead use the function ‘transient-args’, which returns a list of
+     values.  In complex cases it might be necessary to use this
+     variable instead, i.e., if you need access to information beside
+     the value.
+
+
+File: doccZhEUk.info,  Node: Current Prefix Command,  Next: Transient State,  Prev: Current Suffix Command,  Up: Defining New Commands
+
+4.8 Current Prefix Command
+==========================
+
+Function: transient-prefix-object
+     This function returns the current prefix as an object.
+
+     While a transient is being setup or refreshed (which involves
+     preparing its suffixes) the variable ‘transient--prefix’ can be
+     used to access the prefix object.  Thus this is what has to be used
+     in suffix methods such as ‘transient-format-description’, and in
+     object-specific functions that are stored in suffix slots such as
+     ‘description’.
+
+     When a suffix command is invoked (i.e., in its ‘interactive’ form
+     and function body) then the variable ‘transient-current-prefix’ has
+     to be used instead.
+
+     Two distinct variables are needed, because any prefix may itself be
+     used as a suffix of another prefix, and such sub-prefixes have to
+     be able to tell themselves apart from the prefix they were invoked
+     from.
+
+     Regular suffix commands, which are not prefixes, do not have to
+     concern themselves with this distinction, so they can use this
+     function instead.  In the context of a plain suffix, it always
+     returns the value of the appropriate variable.
+
+Variable: transient-current-prefix
+     The transient from which this suffix command was invoked.  The
+     value is a ‘transient-prefix’ object, which holds information
+     associated with the transient prefix command.
+
+Variable: transient-current-command
+     The transient from which this suffix command was invoked.  The
+     value is a symbol, the transient prefix command.
+
+Function: transient-active-prefix &optional prefixes
+     This function returns the active transient object.  It returns
+     ‘nil’ if there is no active transient, if the transient buffer
+     isn’t shown, and while the active transient is suspended (e.g.,
+     while the minibuffer is in use).
+
+     Unlike ‘transient-current-prefix’, which is only ever non-‘nil’ in
+     code that is run directly by a command that is invoked while a
+     transient is current, this function is also suitable for use in
+     asynchronous code, such as timers and callbacks (this function’s
+     main use-case).
+
+     If optional PREFIXES is non-‘nil’, it must be a prefix command
+     symbol or a list of symbols, in which case the active transient
+     object is only returned if it matches one of the PREFIXES.
+
+
+File: doccZhEUk.info,  Node: Transient State,  Prev: Current Prefix Command,  Up: Defining New Commands
+
+4.9 Transient State
+===================
+
+Invoking a transient prefix command “activates” the respective
+transient, i.e., it puts a transient keymap into effect, which binds the
+transient’s infix and suffix commands.
+
+   The default behavior while a transient is active is as follows:
+
+   • Invoking an infix command does not affect the transient state; the
+     transient remains active.
+
+   • Invoking a (non-infix) suffix command “deactivates” the transient
+     state by removing the transient keymap and performing some
+     additional cleanup.
+
+   • Invoking a command that is bound in a keymap other than the
+     transient keymap is disallowed and trying to do so results in a
+     warning.  This does not “deactivate” the transient.
+
+   The behavior can be changed for all suffixes of a particular prefix
+and/or for individual suffixes.  The values should nearly always be
+booleans, but certain functions, called “pre-commands”, can also be
+used.  These functions are named ‘transient--do-VERB’, and the symbol
+‘VERB’ can be used as a shorthand.
+
+   A boolean is interpreted as answering the question "does the
+transient stay active, when this command is invoked?"  ‘t’ means that
+the transient stays active, while ‘nil’ means that invoking the command
+exits the transient.
+
+   Note that when the suffix is a “sub-prefix”, invoking that command
+always activates that sub-prefix, causing the outer prefix to no longer
+be active and displayed.  Here ‘t’ means that when you exit the inner
+prefix, then the outer prefix becomes active again, while ‘nil’ means
+that all outer prefixes are exited at once.
+
+   • The behavior for non-suffixes can be set for a particular prefix,
+     by the prefix’s ‘transient-non-suffix’ slot to a boolean, a
+     suitable pre-command function, or a shorthand for such a function.
+     See *note Pre-commands for Non-Suffixes::.
+
+   • The common behavior for the suffixes of a particular prefix can be
+     set using the prefix’s ‘transient-suffixes’ slot.
+
+     The value specified in this slot does *not* affect infixes.
+     Because it affects both regular suffixes as well as sub-prefixes,
+     which have different needs, it is best to avoid explicitly
+     specifying a function.
+
+   • The behavior of an individual suffix can be changed using its
+     ‘transient’ slot.  While it is usually best to use a boolean, for
+     this slot it can occasionally make sense to specify a function
+     explicitly.
+
+     Note that this slot can be set when defining a suffix command using
+     ‘transient-define-suffix’ and/or in the definition of the prefix.
+     If set in both places, then the latter takes precedence, as usual.
+
+   The available pre-command functions are documented in the following
+sub-sections.  They are called by ‘transient--pre-command’, a function
+on ‘pre-command-hook’, and the value that they return determines whether
+the transient is exited.  To do so the value of one of the constants
+‘transient--exit’ or ‘transient--stay’ is used (that way we don’t have
+to remember if ‘t’ means “exit” or “stay”).
+
+   Additionally, these functions may change the value of ‘this-command’
+(which explains why they have to be called using ‘pre-command-hook’),
+call ‘transient-export’, ‘transient--stack-zap’ or
+‘transient--stack-push’; and set the values of ‘transient--exitp’,
+‘transient--helpp’ or ‘transient--editp’.
+
+   For completeness sake, some notes about complications:
+
+   • The transient-ness of certain built-in suffix commands is specified
+     using ‘transient-predicate-map’.  This is a special keymap, which
+     binds commands to pre-commands (as opposed to keys to commands) and
+     takes precedence over the prefix’s ‘transient-suffix’ slot, but not
+     the suffix’s ‘transient’ slot.
+
+   • While a sub-prefix is active we nearly always want ‘C-g’ to take
+     the user back to the “super-prefix”, even when the other suffixes
+     don’t do that.  However, in rare cases this may not be desirable,
+     in which case ‘replace’ can be used as the value of the
+     sub-prefix’s ‘transient’ slot.
+
+Pre-commands for Infixes
+------------------------
+
+The default for infixes is ‘transient--do-stay’.  This is also the only
+function that makes sense for infixes, which is why this predicate is
+used even if the value of the prefix’s ‘transient-suffix’ slot is ‘t’.
+In extremely rare cases, one might want to use something else, which can
+be done by setting the infix’s ‘transient’ slot directly.
+
+Function: transient–do-stay
+     Call the command without exporting variables and stay transient.
+
+Pre-commands for Suffixes
+-------------------------
+
+By default, invoking a suffix causes the transient to be exited.
+
+   The behavior for an individual suffix command can be changed by
+setting its ‘transient’ slot to a boolean (which is highly recommended),
+or to one of the following pre-commands.
+
+Function: transient–do-exit
+     Call the command after exporting variables and exit the transient.
+
+Function: transient–do-return
+     Call the command after exporting variables and return to the parent
+     prefix.  If there is no parent prefix, then call
+     ‘transient--do-exit’.
+
+Function: transient–do-call
+     Call the command after exporting variables and stay transient.
+
+   The following pre-commands are only suitable for sub-prefixes.  It is
+not necessary to explicitly use these predicates because the correct
+predicate is automatically picked based on the value of the ‘transient’
+slot for the sub-prefix itself.
+
+Function: transient–do-recurse
+     Call the transient prefix command, preparing for return to outer
+     transient.
+
+     Whether we actually return to the parent transient is ultimately
+     under the control of each invoked suffix.  The difference between
+     this pre-command and ‘transient--do-stack’ is that it changes the
+     value of the ‘transient-suffix’ slot to ‘t’.
+
+     If there is no parent transient, then only call this command and
+     skip the second step.
+
+Function: transient–do-stack
+     Call the transient prefix command, stacking the active transient.
+     Push the active transient to the transient stack.
+
+     Unless ‘transient--do-recurse’ is explicitly used, this pre-command
+     is automatically used for suffixes that are prefixes themselves,
+     i.e., for sub-prefixes.
+
+Function: transient–do-replace
+     Call the transient prefix command, replacing the active transient.
+     Do not push the active transient to the transient stack.
+
+     Unless ‘transient--do-recurse’ is explicitly used, this pre-command
+     is automatically used for suffixes that are prefixes themselves,
+     i.e., for sub-prefixes.
+
+Function: transient–do-suspend
+     Suspend the active transient, saving the transient stack.
+
+     This is used by the command ‘transient-suspend’ and optionally also
+     by “external events” such as ‘handle-switch-frame’.  Such bindings
+     should be added to ‘transient-predicate-map’.
+
+Pre-commands for Non-Suffixes
+-----------------------------
+
+By default, non-suffixes (commands that are bound in other keymaps
+beside the transient keymap) cannot be invoked.  Trying to invoke such a
+command results in a warning and the transient stays active.
+
+   If you want a different behavior, then set the ‘transient-non-suffix’
+slot of the transient prefix command.  The value should be a boolean,
+answering the question, "is it allowed to invoke non-suffix commands?, a
+pre-command function, or a shorthand for such a function.
+
+   If the value is ‘t’, then non-suffixes can be invoked, when it is
+‘nil’ (the default) then they cannot be invoked.
+
+   The only other recommended value is ‘leave’.  If that is used, then
+non-suffixes can be invoked, but if one is invoked, then that exits the
+transient.
+
+Function: transient–do-warn
+     Call ‘transient-undefined’ and stay transient.
+
+Function: transient–do-stay
+     Call the command without exporting variables and stay transient.
+
+Function: transient–do-leave
+     Call the command without exporting variables and exit the
+     transient.
+
+Special Pre-Commands
+--------------------
+
+Function: transient–do-quit-one
+     If active, quit help or edit mode, else exit the active transient.
+
+     This is used when the user pressed ‘C-g’.
+
+Function: transient–do-quit-all
+     Exit all transients without saving the transient stack.
+
+     This is used when the user pressed ‘C-q’.
+
+Function: transient–do-suspend
+     Suspend the active transient, saving the transient stack.
+
+     This is used when the user pressed ‘C-z’.

+
+5 Classes and Methods
+*********************
+
+Transient uses classes and generic functions to make it possible to
+define new types of suffix and prefix commands, which are similar to
+existing types, but behave differently in some respects.
+
+   Every prefix, infix and suffix command is associated with an object,
+which holds information, which controls certain aspects of its behavior.
+This happens in two ways.
+
+   • Associating a command with a certain class gives the command a
+     type.  This makes it possible to use generic functions to do
+     certain things that have to be done differently depending on what
+     type of command it acts on.
+
+     That in turn makes it possible for third-parties to add new types
+     without having to convince the maintainer of Transient, that that
+     new type is important enough to justify adding a special case to a
+     dozen or so functions.
+
+   • Associating a command with an object makes it possible to easily
+     store information that is specific to that particular command.
+
+     Two commands may have the same type, but obviously their key
+     bindings and descriptions still have to be different, for example.
+
+     The values of some slots are functions.  The ‘reader’ slot for
+     example holds a function that is used to read a new value for an
+     infix command.  The values of such slots are regular functions.
+
+     Generic functions are used when a function should do something
+     different based on the type of the command, i.e., when all commands
+     of a certain type should behave the same way but different from the
+     behavior for other types.  Object slots that hold a regular
+     function as value are used when the task that they perform is
+     likely to differ even between different commands of the same type.

+
+5.1 Group Classes
+=================
+
+The type of a group can be specified using the ‘:class’ property at the
+beginning of the class specification, e.g., ‘[:class transient-columns
+...]’ in a call to ‘transient-define-prefix’.
+
+   • The abstract ‘transient-child’ class is the base class of both
+     ‘transient-group’ (and therefore all groups) as well as of
+     ‘transient-suffix’ (and therefore all suffix and infix commands).
+
+     This class exists because the elements (or “children”) of certain
+     groups can be other groups instead of suffix and infix commands.
+
+   • The abstract ‘transient-group’ class is the superclass of all other
+     group classes.
+
+   • The ‘transient-column’ class is the simplest group.
+
+     This is the default “flat” group.  If the class is not specified
+     explicitly and the first element is not a vector (i.e., not a
+     group), then this class is used.
+
+     This class displays each element on a separate line.
+
+   • The ‘transient-row’ class displays all elements on a single line.
+
+   • The ‘transient-columns’ class displays commands organized in
+     columns.
+
+     Direct elements have to be groups whose elements have to be
+     commands or strings.  Each subgroup represents a column.  This
+     class takes care of inserting the subgroups’ elements.
+
+     This is the default “nested” group.  If the class is not specified
+     explicitly and the first element is a vector (i.e., a group), then
+     this class is used.
+
+   • The ‘transient-subgroups’ class wraps other groups.
+
+     Direct elements have to be groups whose elements have to be
+     commands or strings.  This group inserts an empty line between
+     subgroups.  The subgroups themselves are responsible for displaying
+     their elements.
+

+
+5.2 Group Methods
+=================
+
+Function: transient-setup-children group children
+     This generic function can be used to setup the children or a group.
+
+     The default implementation usually just returns the children
+     unchanged, but if the ‘setup-children’ slot of GROUP is non-‘nil’,
+     then it calls that function with CHILDREN as the only argument and
+     returns the value.
+
+     The children are given as a (potentially empty) list consisting of
+     either group or suffix specifications.  These functions can make
+     arbitrary changes to the children including constructing new
+     children from scratch.
+
+Function: transient–insert-group group
+     This generic function formats the group and its elements and
+     inserts the result into the current buffer, which is a temporary
+     buffer.  The contents of that buffer are later inserted into the
+     popup buffer.
+
+     Functions that are called by this function may need to operate in
+     the buffer from which the transient was called.  To do so they can
+     temporarily make the ‘transient--shadowed-buffer’ the current
+     buffer.

+
+5.3 Prefix Classes
+==================
+
+Transient itself provides a single class for prefix commands,
+‘transient-prefix’, but package authors may wish to define specialized
+classes.  Doing so makes it possible to change the behavior of the set
+of prefix commands that use that class, by implementing specialized
+methods for certain generic functions (see *note Prefix Methods::).
+
+   A transient prefix command’s object is stored in the
+‘transient--prefix’ property of the command symbol.  While a transient
+is active, a clone of that object is stored in the variable
+‘transient--prefix’.  A clone is used because some changes that are made
+to the active transient’s object should not affect later invocations.
+
+
+File: doccZhEUk.info,  Node: Suffix Classes,  Next: Prefix Methods,  Prev: Prefix Classes,  Up: Classes and Methods
+
+5.4 Suffix Classes
+==================
+
+   • All suffix and infix classes derive from ‘transient-suffix’, which
+     in turn derives from ‘transient-child’, from which
+     ‘transient-group’ also derives (see *note Group Classes::).
+
+   • All infix classes derive from the abstract ‘transient-infix’ class,
+     which in turn derives from the ‘transient-suffix’ class.
+
+     Infixes are a special type of suffixes.  The primary difference is
+     that infixes always use the ‘transient--do-stay’ pre-command, while
+     non-infix suffixes use a variety of pre-commands (see *note
+     Transient State::).  Doing that is most easily achieved by using
+     this class, though theoretically it would be possible to define an
+     infix class that does not do so.  If you do that then you get to
+     implement many methods.
+
+     Also, infixes and non-infix suffixes are usually defined using
+     different macros (see *note Defining Suffix and Infix Commands::).
+
+   • Classes used for infix commands that represent arguments should be
+     derived from the abstract ‘transient-argument’ class.
+
+   • The ‘transient-switch’ class (or a derived class) is used for infix
+     arguments that represent command-line switches (arguments that do
+     not take a value).
+
+   • The ‘transient-option’ class (or a derived class) is used for infix
+     arguments that represent command-line options (arguments that do
+     take a value).
+
+   • The ‘transient-switches’ class can be used for a set of mutually
+     exclusive command-line switches.
+
+   • The ‘transient-files’ class can be used for a ‘--’ argument that
+     indicates that all remaining arguments are files.
+
+   • Classes used for infix commands that represent variables should
+     derived from the abstract ‘transient-variable’ class.
+
+   • The ‘transient-information’ and ‘transient-information*’ classes
+     are special in that suffixes that use these class are not
+     associated with a command and thus also not with any key binding.
+     Such suffixes are only used to display arbitrary information, and
+     that anywhere a suffix can appear.  Display-only suffix
+     specifications take these form:
+
+          ([LEVEL] :info DESCRIPTION [KEYWORD VALUE]...)
+          ([LEVEL] :info* DESCRIPTION [KEYWORD VALUE]...)
+
+     The ‘:info’ and ‘:info*’ keyword arguments replaces the
+     ‘:description’ keyword used for other suffix classes.  Other
+     keyword arguments that you might want to set, include ‘:face’,
+     predicate keywords (such as ‘:if’ and ‘:inapt-if’), and ‘:format’.
+     By default the value of ‘:format’ includes ‘%k’, which for this
+     class is replaced with the empty string or spaces, if keys are
+     being padded in the containing group.
+
+     The only difference between these two classes is that ‘:info*’
+     aligns its description with the descriptions of suffix commands,
+     while for ‘:info’ the description bleeds into the area where
+     suffixes display their key bindings.
+
+   • The ‘transient-lisp-variable’ class can be used to show and change
+     the value of lisp variables.  This class is not fully featured yet
+     and it is somewhat likely that future improvements won’t be fully
+     backward compatible.
+
+   • The ‘transient-describe-target’ class is used by the command
+     ‘transient-describe’.
+
+   • The ‘transient-value-preset’ class is used to implement the command
+     ‘transient-preset’, which activates a value preset.
+
+   Magit defines additional classes, which can serve as examples for the
+fancy things you can do without modifying Transient.  Some of these
+classes will likely get generalized and added to Transient.  For now
+they are very much subject to change and not documented.

+5.5 Prefix Methods
+==================
+
+To get information about the methods implementing these generic
+functions use ‘describe-function’.
+
+Function: transient-init-value obj
+     This generic function sets the initial value of the object OBJ.
+     Methods exist for both prefix and suffix objects.
+
+     The default method for prefix objects sets the value of OBJ’s
+     ‘value’ slot to the set, saved or default value.  The value that is
+     set for the current session is preferred over the saved value,
+     which is preferred over the default value.
+
+     The default value is determined using the generic function
+     ‘transient-default-value’.  If you need to change how the value for
+     a prefix class is determined, its usually sufficient to implement a
+     method for that function.
+
+Function: transient-default-value obj
+     This generic function returns the default value of the object OBJ.
+     Methods exist for both prefix and suffix objects.
+
+     The default method for prefix objects returns the value of the
+     ‘default-value’ slot if that is bound and not a function.  If it is
+     a function, that is called to get the value.  If the slot is
+     unbound, ‘nil’ is returned.
+
+Function: transient-prefix-value obj
+     This generic function returns the value of the prefix object OBJ.
+     The respective generic function for infix and suffix objects is
+     named ‘transient-infix-value’.
+
+Function: transient-init-scope obj
+     This generic function sets the scope of the object OBJ.  Methods
+     exist for both prefix and suffix objects.
+
+     This function is called for all prefix and suffix commands, but
+     unless a concrete method is implemented this falls through to the
+     default implementation, which is a noop.
+
+   ‘transient-set-value’, ‘transient-save-value’,
+‘transient-reset-value’, ‘transient--history-key’,
+‘transient--history-push’ and ‘transient--history-init’ are other
+generic functions dealing with the value of prefix objects.  See their
+doc-strings for more information.
+
+   ‘transient-show-help’ is another generic function implemented for
+prefix commands.  The default method effectively describes the command
+using ‘describe-function’.

+functions use ‘describe-function’.

+
+5.6.1 Suffix Value Methods
+--------------------------
+
+Function: transient-init-value obj
+     This generic function sets the initial value of the object OBJ.
+     Methods exist for both prefix and suffix objects.
+
+     For ‘transient-argument’ objects this function handles setting the
+     value by itself.
+
+     For other ‘transient-suffix’ objects (including ‘transient-infix’
+     objects), this calls ‘transient-default-value’ and uses the value
+     returned by that, unless it is the special value ‘eieio--unbound’,
+     which indicates that there is no default value.  Since that is what
+     the default method for ‘transient-suffix’ objects does, both of
+     these functions effectively are noops for these classes.
+
+     If you implement a class that derives from ‘transient-infix’
+     directly, then you must implement a dedicated method for this
+     function and/or ‘transient-default-value’.
+
+Function: transient-default-value obj
+     This generic function returns the default value of the object OBJ.
+     Methods exist for both prefix and suffix objects.
+
+Function: transient-infix-read obj
+     This generic function determines the new value of the infix object
+     OBJ.
+
+     This function merely determines the value; ‘transient-infix-set’ is
+     used to actually store the new value in the object.
+
+     For most infix classes this is done by reading a value from the
+     user using the reader specified by the ‘reader’ slot (using the
+     ‘transient-infix-value’ method described below).
+
+     For some infix classes the value is changed without reading
+     anything in the minibuffer, i.e., the mere act of invoking the
+     infix command determines what the new value should be, based on the
+     previous value.
+
+Function: transient-prompt obj
+     This generic function returns the prompt to be used to read infix
+     object OBJ’s value.
+
+Function: transient-infix-set obj value
+     This generic function sets the value of infix object OBJ to VALUE.
+
+Function: transient-infix-value obj
+     This generic function returns the value of the suffix object OBJ.
+
+     This function is called by ‘transient-args’ (which see), meaning
+     this function is how the value of a transient is determined so that
+     the invoked suffix command can use it.
+
+     Currently most values are strings, but that is not set in stone.
+     ‘nil’ is not a value, it means “no value”.
+
+     Usually only infixes have a value, but see the method for
+     ‘transient-suffix’.
+
+Function: transient-init-scope obj
+     This generic function sets the scope of the object OBJ.  Methods
+     exist for both prefix and suffix objects.
+
+     The scope is actually a property of the transient prefix, not of
+     individual suffixes.  However it is possible to invoke a suffix
+     command directly instead of from a transient.  In that case, if the
+     suffix expects a scope, then it has to determine that itself and
+     store it in its ‘scope’ slot.
+
+     This function is called for all prefix and suffix commands, but
+     unless a concrete method is implemented, this falls through to the
+     default implementation, which is a noop.
+
+
+File: doccZhEUk.info,  Node: Suffix Format Methods,  Prev: Suffix Value Methods,  Up: Suffix Methods
+
+5.6.2 Suffix Format Methods
+---------------------------
+
+Function: transient-format obj
+     This generic function formats and returns OBJ for display.
+
+     When this function is called, then the current buffer is some
+     temporary buffer.  If you need the buffer from which the prefix
+     command was invoked to be current, then do so by temporarily making
+     ‘transient--source-buffer’ current.
+
+Function: transient-format-key obj
+     This generic function formats OBJ’s ‘key’ for display and returns
+     the result.
+
+Function: transient-format-description obj
+     This generic function formats OBJ’s ‘description’ for display and
+     returns the result.
+
+Function: transient-format-value obj
+     This generic function formats OBJ’s value for display and returns
+     the result.
+
+Function: transient-show-help obj
+     Show help for the prefix, infix or suffix command represented by
+     OBJ.
+
+     Regardless of OBJ’s type, if its ‘show-help’ slot is non-‘nil’,
+     that must be a function, which takes OBJ is its only argument.  It
+     must prepare, display and return a buffer, and select the window
+     used to display it.  The ‘transient-show-help-window’ macro is
+     intended for use in such functions.
+
+     For prefixes, show the info manual, if that is specified using the
+     ‘info-manual’ slot.  Otherwise, show the manpage if that is
+     specified using the ‘man-page’ slot.  Otherwise, show the command’s
+     documentation string.
+
+     For suffixes, show the command’s documentation string.
+
+     For infixes, show the manpage if that is specified.  Otherwise show
+     the command’s documentation string.
+
+Macro: transient-with-help-window &rest body
+     Evaluate BODY, send output to ‘*Help*’ buffer, and display it in a
+     window.  Select the help window, and make the help buffer current
+     and return it.
+
+Function: transient-show-summary obj &optional return
+     This generic function shows or, if optional RETURN is non-‘nil’,
+     returns a brief summary about the command at point or hovered with
+     the mouse.
+
+     This function is called when the mouse is moved over a command and
+     (if the value of ‘transient-enable-popup-navigation’ is ‘verbose’)
+     when the user navigates to a command using the keyboard.
+
+     If OBJ’s ‘summary’ slot is a string, that is used.  If ‘summary’ is
+     a function, that is called with OBJ as the only argument and the
+     returned string is used.  If ‘summary’ is or returns something
+     other than a string or ‘nil’, no summary is shown.  If ‘summary’ is
+     or returns ‘nil’, the first line of the documentation string is
+     used, if any.
+
+     If RETURN is non-‘nil’, this function returns the summary instead
+     of showing it.  This is used when a tooltip is needed.

+
+5.7 Prefix Slots
+================
+
+Value and Scope
+---------------
+
+   • ‘default-value’ The default value of the prefix.  Use the keyword
+     argument ‘:value’ (sic) to set this slot in the definition of a
+     prefix.
+
+   • ‘init-value’ A function that is responsible for setting the
+     object’s value.  If bound, then this is called with the object as
+     the only argument.  Usually this is not bound, in which case the
+     object’s primary ‘transient-init-value’ method is called instead.
+
+   • ‘history-key’ If multiple prefix commands should share a single
+     value, then this slot has to be set to the same value for all of
+     them.  You probably don’t want that.
+
+   • ‘incompatible’ A list of lists.  Each sub-list specifies a set of
+     mutually exclusive arguments.  Enabling one of these arguments
+     causes the others to be disabled.  An argument may appear in
+     multiple sub-lists.  Arguments must me given in the same form as
+     used in the ‘argument’ or ‘argument-format’ slot of the respective
+     suffix objects, usually something like ‘--switch’ or ‘--option=%s’.
+     For options and ‘transient-switches’ suffixes it is also possible
+     to match against a specific value, as returned by
+     ‘transient-infix-value’, for example, ‘--option=one’.
+
+   • ‘scope’ For some transients it might be necessary to have a sort of
+     secondary value, called a “scope”.  See ‘transient-define-prefix’.
+
+Behavior
+--------
+
+   • ‘transient-suffix’, ‘transient-non-suffix’ and
+     ‘transient-switch-frame’ play a part when determining whether the
+     currently active transient prefix command remains active/transient
+     when a suffix or arbitrary non-suffix command is invoked.  See
+     *note Transient State::.
+
+   • ‘refresh-suffixes’ Normally suffix objects and keymaps are only
+     setup once, when the prefix is invoked.  Setting this to ‘t’,
+     causes them to be recreated after every command.  This is useful
+     when using ‘:if...’ predicates, and those need to be rerun for some
+     reason.  Doing this is somewhat costly, and there is a risk of
+     losing state, so this is disabled by default and still considered
+     experimental.
+
+   • ‘environment’ A function used to establish an environment while
+     initializing, refreshing or redisplaying a transient prefix menu.
+     This is useful to establish a cache, in case multiple suffixes
+     require the same expensive work.  The provided function is called
+     with at least one argument, the function for which it establishes
+     the environment.  It must ‘funcall’ that function with no
+     arguments.  During initialization the second argument is the prefix
+     object being initialized.  This slot is still experimental.
+
+Appearance
+----------
+
+   • ‘display-action’ determines how this prefix is displayed,
+     overriding ‘transient-display-buffer-action’.  It should have the
+     same type.
+
+   • ‘mode-line-format’ is this prefix’s mode line format, overriding
+     ‘transient-mode-line-format’.  It should have the same type.
+
+   • ‘column-widths’ is only respected inside ‘transient-columns’ groups
+     and allows aligning columns across separate instances of that.  A
+     list of integers.
+
+   • ‘variable-pitch’ controls whether alignment is done pixel-wise to
+     account for use of variable-pitch characters, which is useful,
+     e.g., when using emoji.
+
+Documentation
+-------------
+
+   • ‘show-help’, ‘man-page’ or ‘info-manual’ can be used to specify the
+     documentation for the prefix and its suffixes.  The command
+     ‘transient-help’ uses the function ‘transient-show-help’ (which
+     see) to lookup and use these values.
+
+   • ‘suffix-description’ can be used to specify a function which
+     provides fallback descriptions for suffixes that lack a
+     description.  This is intended to be temporarily used when
+     implementing of a new prefix command, at which time
+     ‘transient-command-summary-or-name’ is a useful value.
+
+Internal
+--------
+
+These slots are mostly intended for internal use.  They should not be
+set in calls to ‘transient-define-prefix’.
+
+   • ‘prototype’ When a transient prefix command is invoked, then a
+     clone of that object is stored in the global variable
+     ‘transient--prefix’ and the prototype is stored in the clone’s
+     ‘prototype’ slot.
+
+   • ‘command’ The command, a symbol.  Each transient prefix command
+     consists of a command, which is stored in a symbol’s function slot
+     and an object, which is stored in the ‘transient--prefix’ property
+     of the same symbol.
+
+   • ‘level’ The level of the prefix commands.  The suffix commands
+     whose layer is equal or lower are displayed.  See *note Enabling
+     and Disabling Suffixes::.
+
+   • ‘value’ The likely outdated value of the prefix.  Instead of
+     accessing this slot directly you should use the function
+     ‘transient-get-value’, which is guaranteed to return the up-to-date
+     value.
+
+   • ‘history’ and ‘history-pos’ are used to keep track of historic
+     values.  Unless you implement your own ‘transient-infix-read’
+     method you should not have to deal with these slots.
+
+   • ‘unwind-suffix’ is used internally to ensure transient state is
+     properly exited, even in case of an error.
+
+

+
+5.8 Suffix Slots
+================
+
+Here we document most of the slots that are only available for suffix
+objects.  Some slots are shared by suffix and group objects, they are
+documented in *note Predicate Slots::.
+
+   Also see *note Suffix Classes::.
+
+Slots of ‘transient-child’
+--------------------------
+
+This is the abstract superclass of ‘transient-suffix’ and
+‘transient-group’.  This is where the shared ‘if*’ and ‘inapt-if*’ slots
+(see *note Predicate Slots::), the ‘level’ slot (see *note Enabling and
+Disabling Suffixes::), and the ‘advice’ and ‘advice*’ slots (see *note
+Slots of transient-suffix::) are defined.
+
+   • ‘parent’ The object for the parent group.
+
+Slots of ‘transient-suffix’
+---------------------------
+
+   • ‘key’ The key, a key vector or a key description string.
+
+   • ‘command’ The command, a symbol.
+
+   • ‘transient’ Whether to stay transient.  See *note Transient
+     State::.
+
+   • ‘format’ The format used to display the suffix in the popup buffer.
+     It must contain the following %-placeholders:
+
+        • ‘%k’ For the key.
+        • ‘%d’ For the description.
+        • ‘%v’ For the infix value.  Non-infix suffixes don’t have a
+          value.
+
+   • ‘description’ The description, either a string or a function, which
+     is called with zero or one argument (the suffix object), and
+     returns a string.
+
+   • ‘face’ Face used for the description.  In simple cases it is easier
+     to use this instead of using a function as ‘description’ and adding
+     the styling there.  ‘face’ is appended using
+     ‘add-face-text-property’.
+
+   • ‘show-help’ A function used to display help for the suffix.  If
+     unspecified, the prefix controls how help is displayed for its
+     suffixes.  See also function ‘transient-show-help’.
+
+   • ‘summary’ The summary displayed in the echo area, or as a tooltip.
+     If this is ‘nil’, which it usually should be, the first line of the
+     documentation string is used instead.  See ‘transient-show-summary’
+     for details.
+
+   • ‘definition’ A command, which is used if the body is omitted when
+     defining a command using ‘transient-define-suffix’.
+
+   The following two slots are experimental.  They can also be set for a
+group, in which case they apply to all suffixes in that group, except
+for suffixes that set the same slot to a non-nil value.
+
+   • ‘advice’ A function used to advise the command.  The advise is
+     called using ‘(apply advice command args)’, i.e., it behaves like
+     an "around" advice.
+
+   • ‘advice*’ A function used to advise the command.  Unlike ‘advice’,
+     this advises not only the command body but also its ‘interactive’
+     spec.  If both slots are non-nil, ‘advice’ is used for the body and
+     ‘advice*’ is used for the ‘interactive’ form.  When advising the
+     ‘interactive’ spec, called using ‘(funcall advice
+     #'advice-eval-interactive-spec spec)’.
+
+Slots of ‘transient-infix’
+--------------------------
+
+Some of these slots are only meaningful for some of the subclasses.
+They are defined here anyway to allow sharing certain methods.
+
+   • ‘argument’ The long argument, e.g., ‘--verbose’.
+
+   • ‘shortarg’ The short argument, e.g., ‘-v’.
+
+   • ‘value’ The value.  Should not be accessed directly.
+
+   • ‘init-value’ Function that is responsible for setting the object’s
+     value.  If bound, then this is called with the object as the only
+     argument.  Usually this is not bound, in which case the object’s
+     primary ‘transient-init-value’ method is called instead.
+
+   • ‘unsavable’ Whether the value of the suffix is not saved as part of
+     the prefixes.
+
+   • ‘multi-value’ For options, whether the option can have multiple
+     values.  If this is non-‘nil’, then the values are read using
+     ‘completing-read-multiple’ by default and if you specify your own
+     reader, then it should read the values using that function or
+     similar.
+
+     Supported non-‘nil’ values are:
+
+        • Use ‘rest’ for an option that can have multiple values.  This
+          is useful e.g., for an ‘--’ argument that indicates that all
+          remaining arguments are files (such as ‘git log -- file1
+          file2’).
+
+          In the list returned by ‘transient-args’ such an option and
+          its values are represented by a single list of the form
+          ‘(ARGUMENT . VALUES)’.
+
+        • Use ‘repeat’ for an option that can be specified multiple
+          times.
+
+          In the list returned by ‘transient-args’ each instance of the
+          option and its value appears separately in the usual from, for
+          example: ‘("--another-argument" "--option=first"
+          "--option=second")’.
+
+     In both cases the option’s values have to be specified in the
+     default value of a prefix using the same format as returned by
+     ‘transient-args’, e.g., ‘("--other" "--o=1" "--o=2" ("--" "f1"
+     "f2"))’.
+
+   • ‘always-read’ For options, whether to read a value on every
+     invocation.  If this is ‘nil’, then options that have a value are
+     simply unset and have to be invoked a second time to set a new
+     value.
+
+   • ‘allow-empty’ For options, whether the empty string is a valid
+     value.
+
+   • ‘history-key’ The key used to store the history.  This defaults to
+     the command name.  This is useful when multiple infixes should
+     share the same history because their values are of the same kind.
+
+   • ‘reader’ The function used to read the value of an infix.  Not used
+     for switches.  The function takes three arguments, PROMPT,
+     INITIAL-INPUT and HISTORY, and must return a string.
+
+   • ‘prompt’ The prompt used when reading the value, either a string or
+     a function that takes the object as the only argument and which
+     returns a prompt string.
+
+   • ‘choices’ A list of valid values, or a function that returns such a
+     list.  The latter is not implemented for ‘transient-switches’,
+     because I couldn’t think of a use-case.  How exactly the choices
+     are used varies depending on the class of the suffix.
+
+Slots of ‘transient-variable’
+-----------------------------
+
+   • ‘variable’ The variable.
+
+Slots of ‘transient-switches’
+-----------------------------
+
+   • ‘argument-format’ The display format.  Must contain ‘%s’, one of
+     the ‘choices’ is substituted for that.  E.g., ‘--%s-order’.
+
+   • ‘argument-regexp’ The regexp used to match any one of the switches.
+     E.g., ‘\\(--\\(topo\\|author-date\\|date\\)-order\\)’.

+
+5.9 Predicate Slots
+===================
+
+Suffix and group objects share two sets of predicate slots that control
+whether a group or suffix should be available depending on some state.
+Only one slot from each set can be used at the same time.  It is
+undefined which slot is honored if you use more than one.
+
+   Predicates from the first group control whether the suffix is present
+in the menu at all.
+
+   • ‘if’ Enable if predicate returns non-‘nil’.
+   • ‘if-not’ Enable if predicate returns ‘nil’.
+   • ‘if-non-nil’ Enable if variable’s value is non-‘nil’.
+   • ‘if-nil’ Enable if variable’s value is ‘nil’.
+   • ‘if-mode’ Enable if major-mode matches value.
+   • ‘if-not-mode’ Enable if major-mode does not match value.
+   • ‘if-derived’ Enable if major-mode derives from value.
+   • ‘if-not-derived’ Enable if major-mode does not derive from value.
+
+   Predicates from the second group control whether the suffix can be
+invoked.  The suffix is shown in the menu regardless, but when it is
+considered "inapt", then it is grayed out to indicated that it currently
+cannot be invoked.
+
+   • ‘inapt-if’ Inapt if predicate returns non-‘nil’.
+   • ‘inapt-if-not’ Inapt if predicate returns ‘nil’.
+   • ‘inapt-if-non-nil’ Inapt if variable’s value is non-‘nil’.
+   • ‘inapt-if-nil’ Inapt if variable’s value is ‘nil’.
+   • ‘inapt-if-mode’ Inapt if major-mode matches value.
+   • ‘inapt-if-not-mode’ Inapt if major-mode does not match value.
+   • ‘inapt-if-derived’ Inapt if major-mode derives from value.
+   • ‘inapt-if-not-derived’ Inapt if major-mode does not derive from
+     value.
+
+   By default these predicates run when the prefix command is invoked,
+but this can be changes, using the ‘refresh-suffixes’ prefix slot.  See
+*note Prefix Slots::.
+
+   One more slot is shared between group and suffix classes, ‘level’.
+Like the slots documented above, it is a predicate, but it is used for a
+different purpose.  The value has to be an integer between 1 and 7.
+‘level’ controls whether a suffix or a group should be available
+depending on user preference.  See *note Enabling and Disabling
+Suffixes::.

+Appendix A FAQ
+**************
+
+A.1 Can I control how the popup buffer is displayed?
+====================================================
+
+Yes, see ‘transient-display-buffer-action’ in *note Configuration::.
+You can also control how the popup buffer is displayed on a case-by-case
+basis by passing ‘:display-action’ to ‘transient-define-prefix’.
+
+A.2 How can I copy text from the popup buffer?
+==============================================
+
+To be able to mark text in Transient’s popup buffer using the mouse, you
+have to add the below binding.  Note that for technical reasons, the
+region won’t be visualized, while doing so.  After you have quit the
+transient popup, you will be able to yank it in another buffer.
+
+     (keymap-set transient-predicate-map
+                 "<mouse-set-region>"
+                 #'transient--do-stay)
+
+A.3 How can I autoload prefix and suffix commands?
+==================================================
+
+If your package only supports Emacs 30, just prefix the definition with
+‘;;;###autoload’.  If your package supports released versions of Emacs,
+you unfortunately have to use a long form autoload comment as described
+in *note (elisp)Autoload::.
+
+     ;;;###autoload (autoload 'magit-dispatch "magit" nil t)
+     (transient-define-prefix magit-dispatch ()
+       ...)
+
+A.4 How does Transient compare to prefix keys and universal arguments?
+======================================================================
+
+See
+<https://github.com/magit/transient/wiki/Comparison-with-prefix-keys-and-universal-arguments>.
+
+A.5 How does Transient compare to Magit-Popup and Hydra?
+========================================================
+
+See
+<https://github.com/magit/transient/wiki/Comparison-with-other-packages>.
+
+A.6 Why did some of the key bindings change?
+============================================
+
+You may have noticed that the bindings for some of the common commands
+do *not* have the prefix ‘C-x’ and that furthermore some of these
+commands are grayed out while others are not.  That unfortunately is a
+bit confusing if the section of common commands is not shown
+permanently, making the following explanation necessary.
+
+   The purpose of usually hiding that section but showing it after the
+user pressed the respective prefix key is to conserve space and not
+overwhelm users with too much noise, while allowing the user to quickly
+list common bindings on demand.
+
+   That however should not keep us from using the best possible key
+bindings.  The bindings that do use a prefix do so to avoid wasting too
+many non-prefix bindings, keeping them available for use in individual
+transients.  The bindings that do not use a prefix and that are *not*
+grayed out are very important bindings that are *always* available, even
+when invoking the “common command key prefix” or *any other*
+transient-specific prefix.  The non-prefix keys that *are* grayed out
+however, are not available when any incomplete prefix key sequence is
+active.  They do not use the “common command key prefix” because it is
+likely that users want to invoke them several times in a row and e.g.,
+‘M-p M-p M-p’ is much more convenient than ‘C-x M-p C-x M-p C-x M-p’.
+
+   You may also have noticed that the “Set” command is bound to ‘C-x s’,
+while Magit-Popup used to bind ‘C-c C-c’ instead.  I have seen several
+users praise the latter binding (sic), so I did not change it
+willy-nilly.  The reason that I changed it is that using different
+prefix keys for different common commands, would have made the temporary
+display of the common commands even more confusing, i.e., after pressing
+‘C-c’ all the bindings that begin with the ‘C-x’ prefix would be grayed
+out.
+
+   Using a single prefix for common commands key means that all other
+potential prefix keys can be used for transient-specific commands
+*without* the section of common commands also popping up.  ‘C-c’ in
+particular is a prefix that I want to (and already do) use for Magit,
+and also using that for a common command would prevent me from doing so.
+
+   (See also the next question.)
+
+A.7 Why does ‘q’ not quit popups anymore?
+=========================================
+
+I agree that ‘q’ is a good binding for commands that quit something.
+This includes quitting whatever transient is currently active, but it
+also includes quitting whatever it is that some specific transient is
+controlling.  The transient ‘magit-blame’ for example binds ‘q’ to the
+command that turns ‘magit-blame-mode’ off.
+
+   So I had to decide if ‘q’ should quit the active transient (like
+Magit-Popup used to) or whether ‘C-g’ should do that instead, so that
+‘q’ could be bound in individual transient to whatever commands make
+sense for them.  Because all other letters are already reserved for use
+by individual transients, I have decided to no longer make an exception
+for ‘q’.
+
+   If you want to get ‘q’’s old binding back then you can do so.  Doing
+that is a bit more complicated than changing a single key binding, so I
+have implemented a function, ‘transient-bind-q-to-quit’ that makes the
+necessary changes.  See its documentation string for more information.

+*************************************
+
+                        Version 3, 29 June 2007
+
+     Copyright © 2007 Free Software Foundation, Inc. <https://fsf.org/>
+
+     Everyone is permitted to copy and distribute verbatim copies of this
+     license document, but changing it is not allowed.
+
+Preamble
+========
+
+The GNU General Public License is a free, copyleft license for software
+and other kinds of works.
+
+   The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program—to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+   When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+   To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+   For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+   Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+   For the developers’ and authors’ protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users’ and
+authors’ sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+   Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users’ freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+   Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+   The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS
+====================
+
+  0. Definitions.
+
+     “This License” refers to version 3 of the GNU General Public
+     License.
+
+     “Copyright” also means copyright-like laws that apply to other
+     kinds of works, such as semiconductor masks.
+
+     “The Program” refers to any copyrightable work licensed under this
+     License.  Each licensee is addressed as “you”.  “Licensees” and
+     “recipients” may be individuals or organizations.
+
+     To “modify” a work means to copy from or adapt all or part of the
+     work in a fashion requiring copyright permission, other than the
+     making of an exact copy.  The resulting work is called a “modified
+     version” of the earlier work or a work “based on” the earlier work.
+
+     A “covered work” means either the unmodified Program or a work
+     based on the Program.
+
+     To “propagate” a work means to do anything with it that, without
+     permission, would make you directly or secondarily liable for
+     infringement under applicable copyright law, except executing it on
+     a computer or modifying a private copy.  Propagation includes
+     copying, distribution (with or without modification), making
+     available to the public, and in some countries other activities as
+     well.
+
+     To “convey” a work means any kind of propagation that enables other
+     parties to make or receive copies.  Mere interaction with a user
+     through a computer network, with no transfer of a copy, is not
+     conveying.
+
+     An interactive user interface displays “Appropriate Legal Notices”
+     to the extent that it includes a convenient and prominently visible
+     feature that (1) displays an appropriate copyright notice, and (2)
+     tells the user that there is no warranty for the work (except to
+     the extent that warranties are provided), that licensees may convey
+     the work under this License, and how to view a copy of this
+     License.  If the interface presents a list of user commands or
+     options, such as a menu, a prominent item in the list meets this
+     criterion.
+
+  1. Source Code.
+
+     The “source code” for a work means the preferred form of the work
+     for making modifications to it.  “Object code” means any non-source
+     form of a work.
+
+     A “Standard Interface” means an interface that either is an
+     official standard defined by a recognized standards body, or, in
+     the case of interfaces specified for a particular programming
+     language, one that is widely used among developers working in that
+     language.
+
+     The “System Libraries” of an executable work include anything,
+     other than the work as a whole, that (a) is included in the normal
+     form of packaging a Major Component, but which is not part of that
+     Major Component, and (b) serves only to enable use of the work with
+     that Major Component, or to implement a Standard Interface for
+     which an implementation is available to the public in source code
+     form.  A “Major Component”, in this context, means a major
+     essential component (kernel, window system, and so on) of the
+     specific operating system (if any) on which the executable work
+     runs, or a compiler used to produce the work, or an object code
+     interpreter used to run it.
+
+     The “Corresponding Source” for a work in object code form means all
+     the source code needed to generate, install, and (for an executable
+     work) run the object code and to modify the work, including scripts
+     to control those activities.  However, it does not include the
+     work’s System Libraries, or general-purpose tools or generally
+     available free programs which are used unmodified in performing
+     those activities but which are not part of the work.  For example,
+     Corresponding Source includes interface definition files associated
+     with source files for the work, and the source code for shared
+     libraries and dynamically linked subprograms that the work is
+     specifically designed to require, such as by intimate data
+     communication or control flow between those subprograms and other
+     parts of the work.
+
+     The Corresponding Source need not include anything that users can
+     regenerate automatically from other parts of the Corresponding
+     Source.
+
+     The Corresponding Source for a work in source code form is that
+     same work.
+
+  2. Basic Permissions.
+
+     All rights granted under this License are granted for the term of
+     copyright on the Program, and are irrevocable provided the stated
+     conditions are met.  This License explicitly affirms your unlimited
+     permission to run the unmodified Program.  The output from running
+     a covered work is covered by this License only if the output, given
+     its content, constitutes a covered work.  This License acknowledges
+     your rights of fair use or other equivalent, as provided by
+     copyright law.
+
+     You may make, run and propagate covered works that you do not
+     convey, without conditions so long as your license otherwise
+     remains in force.  You may convey covered works to others for the
+     sole purpose of having them make modifications exclusively for you,
+     or provide you with facilities for running those works, provided
+     that you comply with the terms of this License in conveying all
+     material for which you do not control copyright.  Those thus making
+     or running the covered works for you must do so exclusively on your
+     behalf, under your direction and control, on terms that prohibit
+     them from making any copies of your copyrighted material outside
+     their relationship with you.
+
+     Conveying under any other circumstances is permitted solely under
+     the conditions stated below.  Sublicensing is not allowed; section
+     10 makes it unnecessary.
+
+  3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
+
+     No covered work shall be deemed part of an effective technological
+     measure under any applicable law fulfilling obligations under
+     article 11 of the WIPO copyright treaty adopted on 20 December
+     1996, or similar laws prohibiting or restricting circumvention of
+     such measures.
+
+     When you convey a covered work, you waive any legal power to forbid
+     circumvention of technological measures to the extent such
+     circumvention is effected by exercising rights under this License
+     with respect to the covered work, and you disclaim any intention to
+     limit operation or modification of the work as a means of
+     enforcing, against the work’s users, your or third parties’ legal
+     rights to forbid circumvention of technological measures.
+
+  4. Conveying Verbatim Copies.
+
+     You may convey verbatim copies of the Program’s source code as you
+     receive it, in any medium, provided that you conspicuously and
+     appropriately publish on each copy an appropriate copyright notice;
+     keep intact all notices stating that this License and any
+     non-permissive terms added in accord with section 7 apply to the
+     code; keep intact all notices of the absence of any warranty; and
+     give all recipients a copy of this License along with the Program.
+
+     You may charge any price or no price for each copy that you convey,
+     and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+     You may convey a work based on the Program, or the modifications to
+     produce it from the Program, in the form of source code under the
+     terms of section 4, provided that you also meet all of these
+     conditions:
+
+       a. The work must carry prominent notices stating that you
+          modified it, and giving a relevant date.
+
+       b. The work must carry prominent notices stating that it is
+          released under this License and any conditions added under
+          section 7.  This requirement modifies the requirement in
+          section 4 to “keep intact all notices”.
+
+       c. You must license the entire work, as a whole, under this
+          License to anyone who comes into possession of a copy.  This
+          License will therefore apply, along with any applicable
+          section 7 additional terms, to the whole of the work, and all
+          its parts, regardless of how they are packaged.  This License
+          gives no permission to license the work in any other way, but
+          it does not invalidate such permission if you have separately
+          received it.
+
+       d. If the work has interactive user interfaces, each must display
+          Appropriate Legal Notices; however, if the Program has
+          interactive interfaces that do not display Appropriate Legal
+          Notices, your work need not make them do so.
+
+     A compilation of a covered work with other separate and independent
+     works, which are not by their nature extensions of the covered
+     work, and which are not combined with it such as to form a larger
+     program, in or on a volume of a storage or distribution medium, is
+     called an “aggregate” if the compilation and its resulting
+     copyright are not used to limit the access or legal rights of the
+     compilation’s users beyond what the individual works permit.
+     Inclusion of a covered work in an aggregate does not cause this
+     License to apply to the other parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+     You may convey a covered work in object code form under the terms
+     of sections 4 and 5, provided that you also convey the
+     machine-readable Corresponding Source under the terms of this
+     License, in one of these ways:
+
+       a. Convey the object code in, or embodied in, a physical product
+          (including a physical distribution medium), accompanied by the
+          Corresponding Source fixed on a durable physical medium
+          customarily used for software interchange.
+
+       b. Convey the object code in, or embodied in, a physical product
+          (including a physical distribution medium), accompanied by a
+          written offer, valid for at least three years and valid for as
+          long as you offer spare parts or customer support for that
+          product model, to give anyone who possesses the object code
+          either (1) a copy of the Corresponding Source for all the
+          software in the product that is covered by this License, on a
+          durable physical medium customarily used for software
+          interchange, for a price no more than your reasonable cost of
+          physically performing this conveying of source, or (2) access
+          to copy the Corresponding Source from a network server at no
+          charge.
+
+       c. Convey individual copies of the object code with a copy of the
+          written offer to provide the Corresponding Source.  This
+          alternative is allowed only occasionally and noncommercially,
+          and only if you received the object code with such an offer,
+          in accord with subsection 6b.
+
+       d. Convey the object code by offering access from a designated
+          place (gratis or for a charge), and offer equivalent access to
+          the Corresponding Source in the same way through the same
+          place at no further charge.  You need not require recipients
+          to copy the Corresponding Source along with the object code.
+          If the place to copy the object code is a network server, the
+          Corresponding Source may be on a different server (operated by
+          you or a third party) that supports equivalent copying
+          facilities, provided you maintain clear directions next to the
+          object code saying where to find the Corresponding Source.
+          Regardless of what server hosts the Corresponding Source, you
+          remain obligated to ensure that it is available for as long as
+          needed to satisfy these requirements.
+
+       e. Convey the object code using peer-to-peer transmission,
+          provided you inform other peers where the object code and
+          Corresponding Source of the work are being offered to the
+          general public at no charge under subsection 6d.
+
+     A separable portion of the object code, whose source code is
+     excluded from the Corresponding Source as a System Library, need
+     not be included in conveying the object code work.
+
+     A “User Product” is either (1) a “consumer product”, which means
+     any tangible personal property which is normally used for personal,
+     family, or household purposes, or (2) anything designed or sold for
+     incorporation into a dwelling.  In determining whether a product is
+     a consumer product, doubtful cases shall be resolved in favor of
+     coverage.  For a particular product received by a particular user,
+     “normally used” refers to a typical or common use of that class of
+     product, regardless of the status of the particular user or of the
+     way in which the particular user actually uses, or expects or is
+     expected to use, the product.  A product is a consumer product
+     regardless of whether the product has substantial commercial,
+     industrial or non-consumer uses, unless such uses represent the
+     only significant mode of use of the product.
+
+     “Installation Information” for a User Product means any methods,
+     procedures, authorization keys, or other information required to
+     install and execute modified versions of a covered work in that
+     User Product from a modified version of its Corresponding Source.
+     The information must suffice to ensure that the continued
+     functioning of the modified object code is in no case prevented or
+     interfered with solely because modification has been made.
+
+     If you convey an object code work under this section in, or with,
+     or specifically for use in, a User Product, and the conveying
+     occurs as part of a transaction in which the right of possession
+     and use of the User Product is transferred to the recipient in
+     perpetuity or for a fixed term (regardless of how the transaction
+     is characterized), the Corresponding Source conveyed under this
+     section must be accompanied by the Installation Information.  But
+     this requirement does not apply if neither you nor any third party
+     retains the ability to install modified object code on the User
+     Product (for example, the work has been installed in ROM).
+
+     The requirement to provide Installation Information does not
+     include a requirement to continue to provide support service,
+     warranty, or updates for a work that has been modified or installed
+     by the recipient, or for the User Product in which it has been
+     modified or installed.  Access to a network may be denied when the
+     modification itself materially and adversely affects the operation
+     of the network or violates the rules and protocols for
+     communication across the network.
+
+     Corresponding Source conveyed, and Installation Information
+     provided, in accord with this section must be in a format that is
+     publicly documented (and with an implementation available to the
+     public in source code form), and must require no special password
+     or key for unpacking, reading or copying.
+
+  7. Additional Terms.
+
+     “Additional permissions” are terms that supplement the terms of
+     this License by making exceptions from one or more of its
+     conditions.  Additional permissions that are applicable to the
+     entire Program shall be treated as though they were included in
+     this License, to the extent that they are valid under applicable
+     law.  If additional permissions apply only to part of the Program,
+     that part may be used separately under those permissions, but the
+     entire Program remains governed by this License without regard to
+     the additional permissions.
+
+     When you convey a copy of a covered work, you may at your option
+     remove any additional permissions from that copy, or from any part
+     of it.  (Additional permissions may be written to require their own
+     removal in certain cases when you modify the work.)  You may place
+     additional permissions on material, added by you to a covered work,
+     for which you have or can give appropriate copyright permission.
+
+     Notwithstanding any other provision of this License, for material
+     you add to a covered work, you may (if authorized by the copyright
+     holders of that material) supplement the terms of this License with
+     terms:
+
+       a. Disclaiming warranty or limiting liability differently from
+          the terms of sections 15 and 16 of this License; or
+
+       b. Requiring preservation of specified reasonable legal notices
+          or author attributions in that material or in the Appropriate
+          Legal Notices displayed by works containing it; or
+
+       c. Prohibiting misrepresentation of the origin of that material,
+          or requiring that modified versions of such material be marked
+          in reasonable ways as different from the original version; or
+
+       d. Limiting the use for publicity purposes of names of licensors
+          or authors of the material; or
+
+       e. Declining to grant rights under trademark law for use of some
+          trade names, trademarks, or service marks; or
+
+       f. Requiring indemnification of licensors and authors of that
+          material by anyone who conveys the material (or modified
+          versions of it) with contractual assumptions of liability to
+          the recipient, for any liability that these contractual
+          assumptions directly impose on those licensors and authors.
+
+     All other non-permissive additional terms are considered “further
+     restrictions” within the meaning of section 10.  If the Program as
+     you received it, or any part of it, contains a notice stating that
+     it is governed by this License along with a term that is a further
+     restriction, you may remove that term.  If a license document
+     contains a further restriction but permits relicensing or conveying
+     under this License, you may add to a covered work material governed
+     by the terms of that license document, provided that the further
+     restriction does not survive such relicensing or conveying.
+
+     If you add terms to a covered work in accord with this section, you
+     must place, in the relevant source files, a statement of the
+     additional terms that apply to those files, or a notice indicating
+     where to find the applicable terms.
+
+     Additional terms, permissive or non-permissive, may be stated in
+     the form of a separately written license, or stated as exceptions;
+     the above requirements apply either way.
+
+  8. Termination.
+
+     You may not propagate or modify a covered work except as expressly
+     provided under this License.  Any attempt otherwise to propagate or
+     modify it is void, and will automatically terminate your rights
+     under this License (including any patent licenses granted under the
+     third paragraph of section 11).
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly and
+     finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from you
+     under this License.  If your rights have been terminated and not
+     permanently reinstated, you do not qualify to receive new licenses
+     for the same material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+     You are not required to accept this License in order to receive or
+     run a copy of the Program.  Ancillary propagation of a covered work
+     occurring solely as a consequence of using peer-to-peer
+     transmission to receive a copy likewise does not require
+     acceptance.  However, nothing other than this License grants you
+     permission to propagate or modify any covered work.  These actions
+     infringe copyright if you do not accept this License.  Therefore,
+     by modifying or propagating a covered work, you indicate your
+     acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+     Each time you convey a covered work, the recipient automatically
+     receives a license from the original licensors, to run, modify and
+     propagate that work, subject to this License.  You are not
+     responsible for enforcing compliance by third parties with this
+     License.
+
+     An “entity transaction” is a transaction transferring control of an
+     organization, or substantially all assets of one, or subdividing an
+     organization, or merging organizations.  If propagation of a
+     covered work results from an entity transaction, each party to that
+     transaction who receives a copy of the work also receives whatever
+     licenses to the work the party’s predecessor in interest had or
+     could give under the previous paragraph, plus a right to possession
+     of the Corresponding Source of the work from the predecessor in
+     interest, if the predecessor has it or can get it with reasonable
+     efforts.
+
+     You may not impose any further restrictions on the exercise of the
+     rights granted or affirmed under this License.  For example, you
+     may not impose a license fee, royalty, or other charge for exercise
+     of rights granted under this License, and you may not initiate
+     litigation (including a cross-claim or counterclaim in a lawsuit)
+     alleging that any patent claim is infringed by making, using,
+     selling, offering for sale, or importing the Program or any portion
+     of it.
+
+  11. Patents.
+
+     A “contributor” is a copyright holder who authorizes use under this
+     License of the Program or a work on which the Program is based.
+     The work thus licensed is called the contributor’s “contributor
+     version”.
+
+     A contributor’s “essential patent claims” are all patent claims
+     owned or controlled by the contributor, whether already acquired or
+     hereafter acquired, that would be infringed by some manner,
+     permitted by this License, of making, using, or selling its
+     contributor version, but do not include claims that would be
+     infringed only as a consequence of further modification of the
+     contributor version.  For purposes of this definition, “control”
+     includes the right to grant patent sublicenses in a manner
+     consistent with the requirements of this License.
+
+     Each contributor grants you a non-exclusive, worldwide,
+     royalty-free patent license under the contributor’s essential
+     patent claims, to make, use, sell, offer for sale, import and
+     otherwise run, modify and propagate the contents of its contributor
+     version.
+
+     In the following three paragraphs, a “patent license” is any
+     express agreement or commitment, however denominated, not to
+     enforce a patent (such as an express permission to practice a
+     patent or covenant not to sue for patent infringement).  To “grant”
+     such a patent license to a party means to make such an agreement or
+     commitment not to enforce a patent against the party.
+
+     If you convey a covered work, knowingly relying on a patent
+     license, and the Corresponding Source of the work is not available
+     for anyone to copy, free of charge and under the terms of this
+     License, through a publicly available network server or other
+     readily accessible means, then you must either (1) cause the
+     Corresponding Source to be so available, or (2) arrange to deprive
+     yourself of the benefit of the patent license for this particular
+     work, or (3) arrange, in a manner consistent with the requirements
+     of this License, to extend the patent license to downstream
+     recipients.  “Knowingly relying” means you have actual knowledge
+     that, but for the patent license, your conveying the covered work
+     in a country, or your recipient’s use of the covered work in a
+     country, would infringe one or more identifiable patents in that
+     country that you have reason to believe are valid.
+
+     If, pursuant to or in connection with a single transaction or
+     arrangement, you convey, or propagate by procuring conveyance of, a
+     covered work, and grant a patent license to some of the parties
+     receiving the covered work authorizing them to use, propagate,
+     modify or convey a specific copy of the covered work, then the
+     patent license you grant is automatically extended to all
+     recipients of the covered work and works based on it.
+
+     A patent license is “discriminatory” if it does not include within
+     the scope of its coverage, prohibits the exercise of, or is
+     conditioned on the non-exercise of one or more of the rights that
+     are specifically granted under this License.  You may not convey a
+     covered work if you are a party to an arrangement with a third
+     party that is in the business of distributing software, under which
+     you make payment to the third party based on the extent of your
+     activity of conveying the work, and under which the third party
+     grants, to any of the parties who would receive the covered work
+     from you, a discriminatory patent license (a) in connection with
+     copies of the covered work conveyed by you (or copies made from
+     those copies), or (b) primarily for and in connection with specific
+     products or compilations that contain the covered work, unless you
+     entered into that arrangement, or that patent license was granted,
+     prior to 28 March 2007.
+
+     Nothing in this License shall be construed as excluding or limiting
+     any implied license or other defenses to infringement that may
+     otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others’ Freedom.
+
+     If conditions are imposed on you (whether by court order, agreement
+     or otherwise) that contradict the conditions of this License, they
+     do not excuse you from the conditions of this License.  If you
+     cannot convey a covered work so as to satisfy simultaneously your
+     obligations under this License and any other pertinent obligations,
+     then as a consequence you may not convey it at all.  For example,
+     if you agree to terms that obligate you to collect a royalty for
+     further conveying from those to whom you convey the Program, the
+     only way you could satisfy both those terms and this License would
+     be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+     Notwithstanding any other provision of this License, you have
+     permission to link or combine any covered work with a work licensed
+     under version 3 of the GNU Affero General Public License into a
+     single combined work, and to convey the resulting work.  The terms
+     of this License will continue to apply to the part which is the
+     covered work, but the special requirements of the GNU Affero
+     General Public License, section 13, concerning interaction through
+     a network will apply to the combination as such.
+
+  14. Revised Versions of this License.
+
+     The Free Software Foundation may publish revised and/or new
+     versions of the GNU General Public License from time to time.  Such
+     new versions will be similar in spirit to the present version, but
+     may differ in detail to address new problems or concerns.
+
+     Each version is given a distinguishing version number.  If the
+     Program specifies that a certain numbered version of the GNU
+     General Public License “or any later version” applies to it, you
+     have the option of following the terms and conditions either of
+     that numbered version or of any later version published by the Free
+     Software Foundation.  If the Program does not specify a version
+     number of the GNU General Public License, you may choose any
+     version ever published by the Free Software Foundation.
+
+     If the Program specifies that a proxy can decide which future
+     versions of the GNU General Public License can be used, that
+     proxy’s public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Program.
+
+     Later license versions may give you additional or different
+     permissions.  However, no additional obligations are imposed on any
+     author or copyright holder as a result of your choosing to follow a
+     later version.
+
+  15. Disclaimer of Warranty.
+
+     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+     APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+     COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS”
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+     INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+     MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE
+     RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
+     SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+     NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+     WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
+     AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+     DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+     CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
+     THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
+     BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+     PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF
+     THE POSSIBILITY OF SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+     If the disclaimer of warranty and limitation of liability provided
+     above cannot be given local legal effect according to their terms,
+     reviewing courts shall apply local law that most closely
+     approximates an absolute waiver of all civil liability in
+     connection with the Program, unless a warranty or assumption of
+     liability accompanies a copy of the Program in return for a fee.
+
+END OF TERMS AND CONDITIONS
+===========================
+
+How to Apply These Terms to Your New Programs
+=============================================
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+   To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least the
+“copyright” line and a pointer to where the full notice is found.
+
+     ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.
+     Copyright (C) YEAR NAME OF AUTHOR
+
+     This program is free software: you can redistribute it and/or modify
+     it under the terms of the GNU General Public License as published by
+     the Free Software Foundation, either version 3 of the License, or (at
+     your option) any later version.
+
+     This program is distributed in the hope that it will be useful, but
+     WITHOUT ANY WARRANTY; without even the implied warranty of
+     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+     General Public License for more details.
+
+     You should have received a copy of the GNU General Public License
+     along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+   Also add information on how to contact you by electronic and paper
+mail.
+
+   If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+     PROGRAM Copyright (C) YEAR NAME OF AUTHOR
+     This program comes with ABSOLUTELY NO WARRANTY; for details type ‘show w’.
+     This is free software, and you are welcome to redistribute it
+     under certain conditions; type ‘show c’ for details.
+
+   The hypothetical commands ‘show w’ and ‘show c’ should show the
+appropriate parts of the General Public License.  Of course, your
+program’s commands might be different; for a GUI interface, you would
+use an “about box”.
+
+   You should also get your employer (if you work as a programmer) or
+school, if any, to sign a “copyright disclaimer” for the program, if
+necessary.  For more information on this, and how to apply and follow
+the GNU GPL, see <https://www.gnu.org/licenses/>.
+
+   The GNU General Public License does not permit incorporating your
+program into proprietary programs.  If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library.  If this is what you want to do, use the
+GNU Lesser General Public License instead of this License.  But first,
+please read <https://www.gnu.org/licenses/why-not-lgpl.html>.

+* Introduction
+
+Transient is the library used to implement the keyboard-driven {{{dfn(menus)}}}
+in Magit.  It is distributed as a separate package, so that it can be
+used to implement similar menus in other packages.
+
+This manual can be bit hard to digest when getting started.  A useful
+resource to get over that hurdle is Psionic K's interactive tutorial,
+available at https://github.com/positron-solutions/transient-showcase.

+** Complexity in CLI programs
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+Complexity tends to grow with time.  How do you manage the complexity
+of commands?  Consider the humble shell command =ls=.  It now has over
+/fifty/ command line options.  Some of these are boolean flags (=ls -l=).
+Some take arguments (=ls --sort=s=).  Some have no effect unless paired
+with other flags (=ls -lh=).  Some are mutually exclusive.  Some shell
+commands even have so many options that they introduce /subcommands/
+(=git branch=, =git commit=), each with their own rich set of options
+(=git branch -f=).
+
+** Using Transient for composing interactive commands
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+What about Emacs commands used interactively?  How do these handle
+options?  One solution is to make many versions of the same command,
+so you don't need to!  Consider: =delete-other-windows= vs.
+=delete-other-windows-vertically= (among many similar examples).
+
+Some Emacs commands will simply prompt you for the next "argument"
+(=M-x switch-to-buffer=).  Another common solution is to use prefix
+arguments which usually start with =C-u=.  Sometimes these are sensibly
+numerical in nature (=C-u 4 M-x forward-paragraph= to move forward 4
+paragraphs).  But sometimes they function instead as boolean
+"switches" (=C-u C-SPACE= to jump to the last mark instead of just
+setting it, =C-u C-u C-SPACE= to unconditionally set the mark).  Since
+there aren't many standards for the use of prefix options, you have to
+read the command's documentation to find out what the possibilities
+are.
+
+But when an Emacs command grows to have a truly large set of options
+and arguments, with dependencies between them, lots of option values,
+etc., these simple approaches just don't scale.  Transient is designed
+to solve this issue.  Think of it as the humble prefix argument =C-u=,
+/raised to the power of 10/.  Like =C-u=, it is key driven.  Like the
+shell, it supports boolean "flag" options, options that take
+arguments, and even "sub-commands", with their own options.  But
+instead of searching through a man page or command documentation,
+well-designed transients /guide/ their users to the relevant set of
+options (and even their possible values!) directly, taking into
+account any important pre-existing Emacs settings.  And while for
+shell commands like =ls=, there is only one way to "execute" (hit
+=Return=!), transients can "execute" using multiple different keys tied
+to one of many self-documenting /actions/ (imagine having 5 different
+colored return keys on your keyboard!).  Transients make navigating
+and setting large, complex groups of command options and arguments
+easy.  Fun even.  Once you've tried it, it's hard to go back to the
+=C-u what can I do here again?= way.
+
+* Usage
+** Invoking Transients
+#+cindex: invoking transients
+
+A transient prefix command is invoked like any other command by
+pressing the key that is bound to that command.  The main difference
+to other commands is that a transient prefix command activates a
+transient keymap, which temporarily binds the transient's infix and
+suffix commands, and that those bindings are displayed in a transient
+menu, displayed in a popup buffer.  Bindings from other keymaps may,
+or may not, be disabled while the transient state is in effect.
+
+There are two kinds of commands that are available after invoking a
+transient prefix command; infix and suffix commands.  Infix commands
+set some value (which is then shown in the popup buffer), without
+leaving the transient.  Suffix commands, on the other hand, usually
+quit the transient and they may use the values set by the infix
+commands, i.e., the infix *arguments*.
+
+Instead of setting arguments to be used by a suffix command, infix
+commands may also set some value by side-effect, e.g., by setting the
+value of some variable.
+
+** Aborting and Resuming Transients
+#+cindex: aborting transients
+#+cindex: resuming transients
+
+#+cindex: quit transient
+To quit the transient without invoking a suffix command press {{{kbd(C-g)}}}.
+
+Key bindings in transient keymaps may be longer than a single event.
+After pressing a valid prefix key, all commands whose bindings do not
+begin with that prefix key are temporarily unavailable and grayed out.
+To abort the prefix key press {{{kbd(C-g)}}} (which in this case only quits the
+prefix key, but not the complete transient).
+
+A transient prefix command can be bound as a suffix of another
+transient.  Invoking such a suffix replaces the current transient
+state with a new transient state, i.e., the available bindings change
+and the information displayed in the popup buffer is updated
+accordingly.  Pressing {{{kbd(C-g)}}} while a nested transient is active only
+quits the innermost transient, causing a return to the previous
+transient.
+
+{{{kbd(C-q)}}} or {{{kbd(C-z)}}} on the other hand always exits all transients.  If you use
+the latter, then you can later resume the stack of transients using
+{{{kbd(M-x transient-resume)}}}.
+
+#+attr_texinfo: :compact t
+- Key: C-g (transient-quit-seq) ::
+- Key: C-g (transient-quit-one) ::
+
+  This key quits the currently active incomplete key sequence, if any,
+  or else the current transient.  When quitting the current transient,
+  it returns to the previous transient, if any.
+
+Transient's predecessor bound {{{kbd(q)}}} instead of {{{kbd(C-g)}}} to the quit command.
+To learn how to get that binding back see ~transient-bind-q-to-quit~'s
+documentation string.
+
+- Key: C-q (transient-quit-all) ::
+
+  This command quits the currently active incomplete key sequence, if
+  any, and all transients, including the active transient and all
+  suspended transients, if any.
+
+- Key: C-z (transient-suspend) ::
+
+  Like ~transient-quit-all~, this command quits an incomplete key
+  sequence, if any, and all transients.  Additionally, it saves the
+  stack of transients so that it can easily be resumed (which is
+  particularly useful if you quickly need to do “something else” and
+  the stack is deeper than a single transient, and/or you have already
+  changed the values of some infix arguments).
+
+  Note that only a single stack of transients can be saved at a time.
+  If another stack is already saved, then saving a new stack discards
+  the previous stack.
+
+- Key: M-x transient-resume ::
+
+  This command resumes the previously suspended stack of transients,
+  if any.
+
+** Common Suffix Commands
+#+cindex: common suffix commands
+
+A few shared suffix commands are available in all transients.  These
+suffix commands are not shown in the popup buffer by default.
+
+This includes the aborting commands mentioned in the previous section,
+as well as some other commands that are all bound to {{{kbdvar(C-x <KEY>)}}}.  After
+{{{kbd(C-x)}}} is pressed, a section featuring all these common commands is
+temporarily shown in the popup buffer.  After invoking one of them,
+the section disappears again.  Note, however, that one of these
+commands is described as “Show common permanently”; invoke that if you
+want the common commands to always be shown for all transients.
+
+- Key: C-x t (transient-toggle-common) ::
+
+  This command toggles whether the generic commands that are common to
+  all transients are always displayed or only after typing the
+  incomplete prefix key sequence {{{kbd(C-x)}}}.  This only affects the current
+  Emacs session.
+
+- User Option: transient-show-common-commands ::
+
+  This option controls whether shared suffix commands are shown
+  alongside the transient-specific infix and suffix commands.  By
+  default, the shared commands are not shown to avoid overwhelming
+  the user with too many options.
+
+  While a transient is active, pressing {{{kbd(C-x)}}} always shows the common
+  commands.  The value of this option can be changed for the current
+  Emacs session by typing {{{kbd(C-x t)}}} while a transient is active.
+
+The other common commands are described in either the previous or in
+one of the following sections.
+
+** Saving Values
+#+cindex: saving values of arguments
+
+After setting the infix arguments in a transient, the user can save
+those arguments for future invocations.
+
+Most transients will start out with the saved arguments when they are
+invoked.  There are a few exceptions, though.  Some transients are
+designed so that the value that they use is stored externally as the
+buffer-local value of some variable.  Invoking such a transient again
+uses the buffer-local value. [fn:1]
+
+If the user does not save the value and just exits using a regular
+suffix command, then the value is merely saved to the transient's
+history.  That value won't be used when the transient is next invoked,
+but it is easily accessible (see [[*Using History]]).
+
+- Key: C-x s (transient-set) ::
+
+  This command saves the value of the active transient for this Emacs
+  session.
+
+- Key: C-x C-s (transient-save) ::
+
+  This command saves the value of the active transient persistently
+  across Emacs sessions.
+
+- Key: C-x C-k (transient-reset) ::
+
+  This command clears the set and saved values of the active transient.
+
+- User Option: transient-values-file ::
+
+  This option names the file that is used to persist the values of
+  transients between Emacs sessions.
+
+[fn:1] ~magit-diff~ and ~magit-log~ are two prominent examples, and their
+handling of buffer-local values is actually a bit more complicated
+than outlined above and even customizable.
+
+** Using History
+#+cindex: value history
+
+Every time the user invokes a suffix command the transient's current
+value is saved to its history.  These values can be cycled through,
+the same way one can cycle through the history of commands that read
+user-input in the minibuffer.
+
+#+attr_texinfo: :compact t
+- Key: C-M-p (transient-history-prev) ::
+- Key: C-x p ::
+
+  This command switches to the previous value used for the active
+  transient.
+
+- Key: C-M-n (transient-history-next) ::
+- Key: C-x n ::
+
+  This command switches to the next value used for the active
+  transient.
+
+In addition to the transient-wide history, infixes can have their own
+history.  When an infix reads user-input using the minibuffer, the
+user can use the regular minibuffer history commands to cycle through
+previously used values.  Usually the same keys as those mentioned
+above are bound to those commands.
+
+Authors of transients should arrange for different infix commands that
+read the same kind of value to also use the same history key (see
+[[*Suffix Slots]]).
+
+Both kinds of history are saved to a file when Emacs is exited.
+
+- User Option: transient-save-history ::
+
+  This option controls whether the history of transient commands is
+  saved when exiting Emacs.
+
+- User Option: transient-history-file ::
+
+  This option names the file that is used to persist the history of
+  transients and their infixes between Emacs sessions.
+
+- User Option: transient-history-limit ::
+
+  This option controls how many history elements are kept at the time
+  the history is saved in ~transient-history-file~.
+
+** Getting Help for Suffix Commands
+#+cindex: getting help
+
+Transients can have many suffixes and infixes that the user might not
+be familiar with.  To make it trivial to get help for these, Transient
+provides access to the documentation directly from the active
+transient.
+
+- Key: C-h (transient-help) ::
+
+  This command enters help mode.  When help mode is active, typing a
+  key shows information about the suffix command that the key normally
+  is bound to (instead of invoking it).  Pressing {{{kbd(C-h)}}} a second time
+  shows information about the /prefix/ command.
+
+  After typing a key, the stack of transient states is suspended and
+  information about the suffix command is shown instead.  Typing {{{kbd(q)}}} in
+  the help buffer buries that buffer and resumes the transient state.
+
+What sort of documentation is shown depends on how the transient was
+defined.  For infix commands that represent command-line arguments
+this ideally shows the appropriate manpage.  ~transient-help~ then tries
+to jump to the correct location within that.  Info manuals are also
+supported.  The fallback is to show the command's documentation
+string, for non-infix suffixes this is usually appropriate.
+
+** Enabling and Disabling Suffixes
+#+cindex: enabling suffixes
+#+cindex: disabling suffixes
+
+The user base of a package that uses transients can be very diverse.
+This is certainly the case for Magit; some users have been using it and
+Git for a decade, while others are just getting started now.
+
+#+cindex: levels
+For that reason a mechanism is needed that authors can use to classify a
+transient's infixes and suffixes along the essentials...everything
+spectrum.  We use the term {{{dfn(levels)}}} to describe that mechanism.
+
+#+cindex: transient-level
+Each suffix command is placed on a level and each transient has a
+level (called {{{dfn(transient-level)}}}), which controls which suffix commands
+are available.  Integers between 1 and 7 (inclusive) are valid levels.
+For suffixes, 0 is also valid; it means that the suffix is not
+displayed at any level.
+
+The levels of individual transients and/or their individual suffixes
+can be changed interactively, by invoking the transient and then
+pressing {{{kbd(C-x l)}}} to enter the “edit” mode, see below.
+
+The default level for both transients and their suffixes is 4.  The
+~transient-default-level~ option only controls the default for
+transients.  The default suffix level is always 4.  The authors of
+transients should place certain suffixes on a higher level, if they
+expect that it won't be of use to most users, and they should place
+very important suffixes on a lower level, so that they remain
+available even if the user lowers the transient level.
+
+- User Option: transient-default-level ::
+
+  This option controls which suffix levels are made available by
+  default.  It sets the transient-level for transients for which the
+  user has not set that individually.
+
+- User Option: transient-levels-file ::
+
+  This option names the file that is used to persist the levels of
+  transients and their suffixes between Emacs sessions.
+
+- Key: C-x l (transient-set-level) ::
+
+  This command enters edit mode.  When edit mode is active, then all
+  infixes and suffixes that are currently usable are displayed along
+  with their levels.  The colors of the levels indicate whether they
+  are enabled or not.  The level of the transient is also displayed
+  along with some usage information.
+
+  In edit mode, pressing the key that would usually invoke a certain
+  suffix instead prompts the user for the level that suffix should be
+  placed on.
+
+  Help mode is available in edit mode.
+
+  To change the transient level press {{{kbd(C-x l)}}} again.
+
+  To exit edit mode press {{{kbd(C-g)}}}.
+
+  Note that edit mode does not display any suffixes that are not
+  currently usable.  ~magit-rebase~, for example, shows different
+  suffixes depending on whether a rebase is already in progress or
+  not.  The predicates also apply in edit mode.
+
+  Therefore, to control which suffixes are available given a certain
+  state, you have to make sure that that state is currently active.
+
+- Key: C-x a (transient-toggle-level-limit) ::
+
+  This command toggle whether suffixes that are on levels higher than
+  the level specified by ~transient-default-level~ are temporarily
+  available anyway.
+
+- Function: transient-set-default-level suffix level ::
+
+  This function sets the default level of the suffix COMMAND to LEVEL.
+
+  If a suffix command appears in multiple menus, it may make sense to
+  consistently change its level in all those menus at once.  For
+  example, the ~--gpg-sign~ argument (which is implemented using the
+  command ~magit:--gpg-sign~), is bound in all of Magit's menu which
+  create commits.  Users who sometimes sign their commits would want
+  that argument to be available in all of these menus, while for users
+  who never sign it is just unnecessary noise in any menus.
+
+  To always make ~--gpg-sign~ available, use:
+
+  #+begin_src emacs-lisp
+    (transient-set-default-level 'magit:--gpg-sign 1)
+  #+end_src
+
+  To never make ~--gpg-sign~ available, use:
+
+  #+begin_src emacs-lisp
+    (transient-set-default-level 'magit:--gpg-sign 0)
+  #+end_src
+
+  This sets the level in the suffix prototype object for this command.
+  Commands only have a suffix prototype if they were defined using one
+  of ~transient-define-argument~, ~transient-define-infix~ and
+  ~transient-define-suffix~.  For all other commands this would signal
+  an error.  (This is one of the reasons why package authors should
+  use one of these functions to define shared suffix commands, and
+  especially shared arguments.)
+
+  If the user changes the level of a suffix in a particular menu,
+  using {{{kbd(C-x l)}}} as shown above, then that obviously shadows the default.
+
+  It is also possible to set the level of a suffix binding in a
+  particular menu, either when defining the menu using
+  ~transient-define-prefix,~ or later using ~transient-insert-suffix~.  If
+  such bindings specify a level, then that also overrides the default.
+  (Per-suffix default levels is a new feature, so you might encounter
+  this quite often.)
+
+** Other Commands
+
+When invoking a transient in a small frame, the transient window may
+not show the complete buffer, making it necessary to scroll, using the
+following commands.  These commands are never shown in the transient
+window, and the key bindings are the same as for ~scroll-up-command~ and
+~scroll-down-command~ in other buffers.
+
+- Command: transient-scroll-up arg ::
+
+  This command scrolls text of transient popup window upward {{{var(ARG)}}}
+  lines.  If {{{var(ARG)}}} is ~nil~, then it scrolls near full screen.  This
+  is a wrapper around ~scroll-up-command~ (which see).
+
+- Command: transient-scroll-down arg ::
+
+  This command scrolls text of transient popup window down {{{var(ARG)}}}
+  lines.  If {{{var(ARG)}}} is ~nil~, then it scrolls near full screen.  This
+  is a wrapper around ~scroll-down-command~ (which see).
+
+The following commands are not available by default.  If you would
+like to use them for all menus, bind them in ~transient-map~.
+
+- Command: transient-copy-menu-text ::
+
+  This command copies the contents of the menu buffer to the kill
+  ring.
+
+- Command: transient-toggle-docstrings ::
+
+  This command toggle between showing suffix descriptions in the menu
+  (as usual) or showing the first lines of the respective docstrings
+  in their place.  For commands that do not have a docstring, always
+  display the suffix description.  Because there likely isn't enough
+  room to display multiple docstrings side-by-side, a single column
+  is used when displaying docstrings.
+
+** Configuration
+
+More options are described in [[* Common Suffix Commands]], in [[* Saving
+Values]], in [[* Using History]] and in [[* Enabling and Disabling Suffixes]].
+
+*** Essential Options
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+Also see [[* Common Suffix Commands]].
+
+- User Option: transient-show-popup ::
+
+  This option controls whether the current transient's infix and
+  suffix commands are shown in the popup buffer.
+
+  - If ~t~ (the default) then the popup buffer is shown as soon as a
+    transient prefix command is invoked.
+
+  - If ~nil~, then the popup buffer is not shown unless the user
+    explicitly requests it, by pressing an incomplete prefix key
+    sequence.
+
+  - If a number, then the a brief one-line summary is shown instead of
+    the popup buffer.  If zero or negative, then not even that summary
+    is shown; only the pressed key itself is shown.
+
+    The popup is shown when the user explicitly requests it by
+    pressing an incomplete prefix key sequence.  Unless this is zero,
+    the popup is shown after that many seconds of inactivity (using
+    the absolute value).
+
+- User Option: transient-show-common-commands ::
+
+  This option controls whether shared suffix commands are shown
+  alongside the transient-specific infix and suffix commands.  By
+  default, the shared commands are not shown to avoid overwhelming
+  the user with too many options.
+
+  While a transient is active, pressing {{{kbd(C-x)}}} always shows the common
+  commands.  The value of this option can be changed for the current
+  Emacs session by typing {{{kbd(C-x t)}}} while a transient is active.
+
+- User Option: transient-show-during-minibuffer-read ::
+
+  This option controls whether the transient menu continues to be
+  displayed while the minibuffer is used to read user input.
+
+  This is only relevant to commands that do not close the menu, such as
+  commands that set infix arguments.  If a command exits the menu, and
+  uses the minibuffer, then the menu is always closed before the
+  minibuffer is entered, irrespective of the value of this option.
+
+  When ~nil~ (the default), hide the menu while the minibuffer is in use.
+  When ~t~, keep showing the menu, but allow for the menu window to be
+  resized, to ensure that completion candidates can be displayed.
+
+  When ~fixed~, keep showing the menu and prevent it from being resized,
+  which may make it impossible to display the completion candidates.  If
+  that ever happens for you, consider using ~t~ or an integer, as described
+  below.
+
+  If the value is ~fixed~ and the menu window uses the full height of its
+  frame, then the former is ignored and resizing is allowed anyway.  This
+  is necessary because individual menus may use unusual display actions
+  different from what ~transient-display-buffer-action~ specifies (likely
+  to display that menu in a side-window).
+
+  When using a third-party mode, which automatically resizes windows
+  (e.g., by calling ~balance-windows~ on ~post-command-hook~), then
+  ~fixed~ (or ~nil~) is likely a better choice than ~t~.
+
+  The value can also be an integer, in which case the behavior depends on
+  whether at least that many lines are left to display windows other than
+  the menu window.  If that is the case, display the menu and preserve the
+  size of that window.  Otherwise, allow resizing the menu window if the
+  number is positive, or hide the menu if it is negative.
+
+- User Option: transient-read-with-initial-input ::
+
+  This option controls whether the last history element is used as the
+  initial minibuffer input when reading the value of an infix argument
+  from the user.  If ~nil~, there is no initial input and the first
+  element has to be accessed the same way as the older elements.
+
+- User Option: transient-enable-popup-navigation ::
+
+  This option controls whether navigation commands are enabled in the
+  transient popup buffer.  If the value is ~verbose~ (the default),
+  brief documentation about the command under point is additionally
+  show in the echo area.
+
+  While a transient is active the transient popup buffer is not the
+  current buffer, making it necessary to use dedicated commands to act
+  on that buffer itself.  If this option is non-~nil~, then the
+  following features are available:
+
+  - {{{kbd(UP)}}} moves the cursor to the previous suffix.
+  - {{{kbd(DOWN)}}} moves the cursor to the next suffix.
+  - {{{kbd(M-RET)}}} invokes the suffix the cursor is on.
+  - {{{kbd(mouse-1)}}} invokes the clicked on suffix.
+  - {{{kbd(C-s)}}} and {{{kbd(C-r)}}} start isearch in the popup buffer.
+
+  By default {{{kbd(M-RET)}}} is bound to ~transient-push-button~, instead of
+  {{{kbd(RET)}}}, because if a transient allows the invocation of non-suffixes,
+  then it is likely, that you would want {{{kbd(RET)}}} to do what it would do
+  if no transient were active."
+
+- User Option: transient-display-buffer-action ::
+
+  This option specifies the action used to display the transient popup
+  buffer.  The transient popup buffer is displayed in a window using
+  {{{codevar((display-buffer BUFFER transient-display-buffer-action))}}}.
+
+  The value of this option has the form {{{codevar((FUNCTION . ALIST))}}},
+  where {{{var(FUNCTION)}}} is a function or a list of functions.  Each such
+  function should accept two arguments: a buffer to display and an
+  alist of the same form as {{{var(ALIST)}}}.  See [[info:elisp#Choosing Window]],
+  for details.
+
+  The default is:
+
+  #+BEGIN_SRC emacs-lisp
+    (display-buffer-in-side-window
+     (side . bottom)
+     (dedicated . t)
+     (inhibit-same-window . t))
+  #+END_SRC
+
+  This displays the window at the bottom of the selected frame.
+  For alternatives see [[info:elisp#Buffer Display Action Functions]],
+  and [[info:elisp#Buffer Display Action Alists]].
+
+  When you switch to a different ACTION, you should keep the ALIST
+  entries for ~dedicated~ and ~inhibit-same-window~ in most cases.
+  Do not drop them because you are unsure whether they are needed;
+  if you are unsure, then keep them.
+
+  Note that the buffer that was current before the transient buffer
+  is shown should remain the current buffer.  Many suffix commands

+
+  It may be possible to display the window in another frame, but
+  whether that works in practice depends on the window-manager.
+  If the window manager selects the new window (Emacs frame),

+  If you change the value of this option, then you might also

+*** Accessibility Options

+:END:
+
+- User Option: transient-force-single-column ::
+
+  This option controls whether the use of a single column to display
+  suffixes is enforced.  This might be useful for users with low

+  dimensions.
+
+*** Auxiliary Options

+:END:
+
+- User Option: transient-mode-line-format ::
+
+  This option controls whether the transient popup buffer has a
+  mode-line, separator line, or neither.
+
+  If ~nil~, then the buffer has no mode-line.  If the buffer is not
+  displayed right above the echo area, then this probably is not a
+  good value.
+
+  If ~line~ (the default) or a natural number, then the buffer has no
+  mode-line, but a line is drawn in its place.  If a number is used,
+  that specifies the thickness of the line.  On termcap frames we
+  cannot draw lines, so there ~line~ and numbers are synonyms for ~nil~.
+
+  The color of the line is used to indicate if non-suffixes are
+  allowed and whether they exit the transient.  The foreground
+  color of ~transient-key-noop~ (if non-suffixes are disallowed),
+  ~transient-key-stay~ (if allowed and transient stays active), or
+  ~transient-key-exit~ (if allowed and they exit the transient) is
+  used to draw the line.
+
+  This user option may be overridden if ~:mode-line-format~ is passed
+  when creating a new prefix with ~transient-define-prefix~.
+
+  Otherwise this can be any mode-line format.  See [[info:elisp#Mode
+  Line Format]], for details.
+
+- User Option: transient-semantic-coloring ::
+
+  This option controls whether colors are used to indicate the
+  transient behavior of commands.
+
+  If non-~nil~, then the key binding of each suffix is colorized to
+  indicate whether it exits the transient state or not.  The color of
+  the prefix is indicated using the line that is drawn when the value
+  of ~transient-mode-line-format~ is ~line~.
+
+- User Option: transient-highlight-mismatched-keys ::
+
+  This option controls whether key bindings of infix commands that do
+  not match the respective command-line argument should be highlighted.
+  For other infix commands this option has no effect.
+
+  When this option is non-~nil~, the key binding for an infix argument
+  is highlighted when only a long argument (e.g., ~--verbose~) is
+  specified but no shorthand (e.g., ~-v~).  In the rare case that a
+  shorthand is specified but the key binding does not match, then it
+  is highlighted differently.
+
+  Highlighting mismatched key bindings is useful when learning the
+  arguments of the underlying command-line tool; you wouldn't want to
+  learn any short-hands that do not actually exist.
+
+  The highlighting is done using one of the faces
+  ~transient-mismatched-key~ and ~transient-nonstandard-key~.
+
+- User Option: transient-substitute-key-function ::
+
+  This function is used to modify key bindings.  If the value of this

+
+  This function is called with one argument, the prefix object, and
+  must return a key binding description, either the existing key
+  description it finds in the ~key~ slot, or the key description that
+  replaces the prefix key.  It could be used to make other
+  substitutions, but that is discouraged.
+
+  For example, {{{kbd(=)}}} is hard to reach using my custom keyboard layout,
+  so I substitute {{{kbd(()}}} for that, which is easy to reach using a layout
+  optimized for lisp.
+
+  #+BEGIN_SRC emacs-lisp

+
+- User Option: transient-align-variable-pitch ::
+
+  This option controls whether columns are aligned pixel-wise in the
+  popup buffer.
+
+  If this is non-~nil~, then columns are aligned pixel-wise to support
+  variable-pitch fonts.  Keys are not aligned, so you should use a
+  fixed-pitch font for the ~transient-key~ face.  Other key faces
+  inherit from that face unless a theme is used that breaks that
+  relationship.
+
+  This option is intended for users who use a variable-pitch font for
+  the ~default~ face.
+
+- User Option: transient-force-fixed-pitch ::
+
+  This option controls whether to force the use of a monospaced font
+  in popup buffer.  Even if you use a proportional font for the
+  ~default~ face, you might still want to use a monospaced font in
+  transient's popup buffer.  Setting this option to ~t~ causes ~default~
+  to be remapped to ~fixed-pitch~ in that buffer.

+- User Option: transient-detect-key-conflicts ::
+
+  This option controls whether key binding conflicts should be
+  detected at the time the transient is invoked.  If so, this results
+  in an error, which prevents the transient from being used.  Because
+  of that, conflicts are ignored by default.
+
+  Conflicts cannot be determined earlier, i.e., when the transient is
+  being defined and when new suffixes are being added, because at that
+  time there can be false-positives.  It is actually valid for
+  multiple suffixes to share a common key binding, provided the
+  predicates of those suffixes prevent that more than one of them is
+  enabled at a time.
+
+- User Option: transient-highlight-higher-levels ::
+
+  This option controls whether suffixes that would not be available by
+  default are highlighted.
+
+  When non-~nil~ then the descriptions of suffixes are highlighted if
+  their level is above 4, the default of ~transient-default-level~.
+  Assuming you have set that variable to 7, this highlights all
+  suffixes that won't be available to users without them making the

+
+* Modifying Existing Transients
+#+cindex: modifying existing transients
+
+To an extent, transients can be customized interactively, see
+[[*Enabling and Disabling Suffixes]].  This section explains how existing
+transients can be further modified non-interactively.  Let's begin
+with an example:
+
+#+begin_src emacs-lisp
+  (transient-append-suffix 'magit-patch-apply "-3"
+    '("-R" "Apply in reverse" "--reverse"))
+#+end_src
+
+This inserts a new infix argument to toggle the ~--reverse~ argument
+after the infix argument that toggles ~-3~ in ~magit-patch-apply~.
+
+The following functions share a few arguments:
+
+- {{{var(PREFIX)}}} is a transient prefix command, a symbol.
+
+- {{{var(SUFFIX)}}} is a transient infix or suffix specification in the same form
+  as expected by ~transient-define-prefix~.  Note that an infix is a
+  special kind of suffix.  Depending on context “suffixes” means
+  “suffixes (including infixes)” or “non-infix suffixes”.  Here it
+  means the former.  See [[*Suffix Specifications]].
+
+  {{{var(SUFFIX)}}} may also be a group in the same form as expected by
+  ~transient-define-prefix~.  See [[*Group Specifications]].
+
+- {{{var(LOC)}}} is a command, a key vector, a key description (a string as
+  returned by ~key-description~), or a list specifying coordinates (the
+  last element may also be a command or key).  For example ~(1 0 -1)~
+  identifies the last suffix (~-1~) of the first subgroup (~0~) of the
+  second group (~1~).
+
+  If {{{var(LOC)}}} is a list of coordinates, then it can be used to identify a
+  group, not just an individual suffix command.
+
+  The function ~transient-get-suffix~ can be useful to determine whether
+  a certain coordination list identifies the suffix or group that you
+  expect it to identify.  In hairy cases it may be necessary to look
+  at the definition of the transient prefix command.
+
+These functions operate on the information stored in the
+~transient--layout~ property of the {{{var(PREFIX)}}} symbol.  Suffix entries in
+that tree are not objects but have the form {{{codevar((LEVEL CLASS PLIST))}}}, where
+{{{var(PLIST)}}} should set at least ~:key~, ~:description~ and ~:command~.
+
+- Function: transient-insert-suffix prefix loc suffix &optional keep-other ::
+- Function: transient-append-suffix prefix loc suffix &optional keep-other ::
+
+  These functions insert the suffix or group {{{var(SUFFIX)}}} into {{{var(PREFIX)}}} before
+  or after {{{var(LOC)}}}.
+
+  Conceptually adding a binding to a transient prefix is similar to
+  adding a binding to a keymap, but this is complicated by the fact
+  that multiple suffix commands can be bound to the same key, provided
+  they are never active at the same time, see [[*Predicate Slots]].
+
+  Unfortunately both false-positives and false-negatives are possible.
+  To deal with the former use non-~nil~ {{{var(KEEP-OTHER.)}}}  The symbol ~always~
+  prevents the removal of a false-positive in some cases where other
+  non-~nil~ values would fail.  To deal with false-negatives remove the
+  conflicting binding separately, using ~transient-remove-suffix~.
+
+- Function: transient-replace-suffix prefix loc suffix ::
+
+  This function replaces the suffix or group at {{{var(LOC)}}} in {{{var(PREFIX)}}} with
+  suffix or group {{{var(SUFFIX)}}}.
+
+- Function: transient-remove-suffix prefix loc ::
+
+  This function removes the suffix or group at {{{var(LOC)}}} in {{{var(PREFIX)}}}.
+
+- Function: transient-get-suffix prefix loc ::
+
+  This function returns the suffix or group at {{{var(LOC)}}} in {{{var(PREFIX)}}}.  The
+  returned value has the form mentioned above.
+
+- Function: transient-suffix-put prefix loc prop value ::
+
+  This function edits the suffix or group at {{{var(LOC)}}} in {{{var(PREFIX)}}}, by setting
+  the {{{var(PROP)}}} of its plist to {{{var(VALUE)}}}.
+
+Most of these functions do not signal an error if they cannot perform
+the requested modification.  The functions that insert new suffixes
+show a warning if {{{var(LOC)}}} cannot be found in {{{var(PREFIX,)}}} without signaling an
+error.  The reason for doing it like this is that establishing a key
+binding (and that is what we essentially are trying to do here) should
+not prevent the rest of the configuration from loading.  Among these
+functions only ~transient-get-suffix~ and ~transient-suffix-put~ may
+signal an error.
+
+* Defining New Commands
+** Technical Introduction
+
+Taking inspiration from prefix keys and prefix arguments, Transient
+implements a similar abstraction involving a prefix command, infix
+arguments and suffix commands.
+
+When the user calls a transient prefix command, a transient
+(temporary) keymap is activated, which binds the transient's infix and
+suffix commands, and functions that control the transient state are
+added to ~pre-command-hook~ and ~post-command-hook~.  The available suffix
+and infix commands and their state are shown in a popup buffer until
+the transient state is exited by invoking a suffix command.
+
+Calling an infix command causes its value to be changed.  How that is
+done depends on the type of the infix command.  The simplest case is
+an infix command that represents a command-line argument that does not
+take a value.  Invoking such an infix command causes the switch to be
+toggled on or off.  More complex infix commands may read a value from
+the user, using the minibuffer.
+
+Calling a suffix command usually causes the transient to be exited;
+the transient keymaps and hook functions are removed, the popup buffer
+no longer shows information about the (no longer bound) suffix
+commands, the values of some public global variables are set, while
+some internal global variables are unset, and finally the command is
+actually called.  Suffix commands can also be configured to not exit
+the transient.
+
+A suffix command can, but does not have to, use the infix arguments in
+much the same way any command can choose to use or ignore the prefix
+arguments.  For a suffix command that was invoked from a transient, the
+variable ~transient-current-suffixes~ and the function ~transient-args~
+serve about the same purpose as the variables ~prefix-arg~ and
+~current-prefix-arg~ do for any command that was called after the prefix
+arguments have been set using a command such as ~universal-argument~.
+
+#+cindex: command dispatchers
+Transient can be used to implement simple “command dispatchers”.  The
+main benefit then is that the user can see all the available commands
+in a popup buffer, which can be thought of as a “menu”.  That is
+useful by itself because it frees the user from having to remember all
+the keys that are valid after a certain prefix key or command.
+Magit's ~magit-dispatch~ (on {{{kbd(C-x M-g)}}}) command is an example of using
+Transient to merely implement a command dispatcher.
+
+In addition to that, Transient also allows users to interactively pass
+arguments to commands.  These arguments can be much more complex than
+what is reasonable when using prefix arguments.  There is a limit to
+how many aspects of a command can be controlled using prefix
+arguments.  Furthermore, what a certain prefix argument means for
+different commands can be completely different, and users have to read
+documentation to learn and then commit to memory what a certain prefix
+argument means to a certain command.
+
+Transient suffix commands, on the other hand, can accept dozens of
+different arguments without the user having to remember anything.
+When using Transient, one can call a command with arguments that are
+just as complex as when calling the same function non-interactively
+from Lisp.
+
+Invoking a transient suffix command with arguments is similar to
+invoking a command in a shell with command-line completion and history
+enabled.  One benefit of the Transient interface is that it remembers
+history not only on a global level (“this command was invoked using
+these arguments, and previously it was invoked using those other
+arguments”), but also remembers the values of individual arguments
+independently.  See [[*Using History]].
+
+After a transient prefix command is invoked, {{{kbdvar(C-h <KEY>)}}} can be used to
+show the documentation for the infix or suffix command that {{{kbdvar(<KEY>)}}} is
+bound to (see [[*Getting Help for Suffix Commands]]), and infixes and
+suffixes can be removed from the transient using {{{kbdvar(C-x l <KEY>)}}}.  Infixes
+and suffixes that are disabled by default can be enabled the same way.
+See [[*Enabling and Disabling Suffixes]].
+
+Transient ships with support for a few different types of specialized
+infix commands.  A command that sets a command line option, for example,
+has different needs than a command that merely toggles a boolean flag.
+Additionally, Transient provides abstractions for defining new types,
+which the author of Transient did not anticipate (or didn't get around
+to implementing yet).
+
+Note that suffix commands also support regular prefix arguments.  A
+suffix command may even be called with both infix and prefix arguments
+at the same time.  If you invoke a command as a suffix of a transient
+prefix command, but also want to pass prefix arguments to it, then
+first invoke the prefix command, and only after doing that invoke the
+prefix arguments, before finally invoking the suffix command.  If you
+instead began by providing the prefix arguments, then those would
+apply to the prefix command, not the suffix command.  Likewise, if you
+want to change infix arguments before invoking a suffix command with
+prefix arguments, then change the infix arguments before invoking the
+prefix arguments.  In other words, regular prefix arguments always
+apply to the next command, and since transient prefix, infix and
+suffix commands are just regular commands, the same applies to them.
+(Regular prefix keys behave differently because they are not commands
+at all, instead they are just incomplete key sequences, and those
+cannot be interrupted with prefix commands.)
+
+** Defining Transients
+
+A transient consists of a prefix command and at least one suffix
+command, though usually a transient has several infix and suffix
+commands.  The below macro defines the transient prefix command *and*
+binds the transient's infix and suffix commands.  In other words, it
+defines the complete transient, not just the transient prefix command
+that is used to invoke that transient.
+
+- Macro: transient-define-prefix name arglist [docstring] [keyword value]... group... [body...] ::
+
+  This macro defines {{{var(NAME)}}} as a transient prefix command and binds the
+  transient's infix and suffix commands.
+
+  {{{var(ARGLIST)}}} are the arguments that the prefix command takes.
+  {{{var(DOCSTRING)}}} is the documentation string and is optional.
+
+  These arguments can optionally be followed by keyword-value pairs.
+  Each key has to be a keyword symbol, either ~:class~ or a keyword
+  argument supported by the constructor of that class.  The
+  ~transient-prefix~ class is used if the class is not specified
+  explicitly.
+
+  {{{var(GROUP)}}}s add key bindings for infix and suffix commands and specify
+  how these bindings are presented in the popup buffer.  At least one
+  {{{var(GROUP)}}} has to be specified.  See [[*Binding Suffix and Infix Commands]].
+
+  The {{{var(BODY)}}} is optional.  If it is omitted, then {{{var(ARGLIST)}}} is ignored and
+  the function definition becomes:
+
+  #+BEGIN_SRC emacs-lisp
+    (lambda ()
+      (interactive)
+      (transient-setup 'NAME))
+  #+END_SRC
+
+  If {{{var(BODY)}}} is specified, then it must begin with an ~interactive~ form
+  that matches {{{var(ARGLIST)}}}, and it must call ~transient-setup~.  It may,
+  however, call that function only when some condition is satisfied.
+
+  #+cindex: scope of a transient
+  All transients have a (possibly ~nil~) value, which is exported when
+  suffix commands are called, so that they can consume that value.
+  For some transients it might be necessary to have a sort of
+  secondary value, called a “scope”.  Such a scope would usually be
+  set in the command's ~interactive~ form and has to be passed to the
+  setup function:
+
+  #+BEGIN_SRC emacs-lisp
+    (transient-setup 'NAME nil nil :scope SCOPE)
+  #+END_SRC
+
+  For example, the scope of the ~magit-branch-configure~ transient is
+  the branch whose variables are being configured.
+
+** Binding Suffix and Infix Commands
+
+The macro ~transient-define-prefix~ is used to define a transient.
+This defines the actual transient prefix command (see [[*Defining
+Transients]]) and adds the transient's infix and suffix bindings, as
+described below.
+
+Users and third-party packages can add additional bindings using
+functions such as ~transient-insert-suffix~ (see [[*Modifying Existing
+Transients]]).  These functions take a “suffix specification” as one of
+their arguments, which has the same form as the specifications used in
+~transient-define-prefix~.
+
+*** Group Specifications
+#+cindex: group specifications
+
+The suffix and infix commands of a transient are organized in groups.
+The grouping controls how the descriptions of the suffixes are
+outlined visually but also makes it possible to set certain properties
+for a set of suffixes.
+
+Several group classes exist, some of which organize suffixes in
+subgroups.  In most cases the class does not have to be specified
+explicitly, but see [[*Group Classes]].
+
+Groups are specified in the call to ~transient-define-prefix~, using
+vectors.  Because groups are represented using vectors, we cannot use
+square brackets to indicate an optional element and instead use curly
+brackets to do the latter.
+
+Group specifications then have this form:
+
+#+begin_src emacs-lisp
+  [{LEVEL} {DESCRIPTION} {KEYWORD VALUE}... ELEMENT...]
+#+end_src
+
+The {{{var(LEVEL)}}} is optional and defaults to 4.  See [[*Enabling and Disabling
+Suffixes]].
+
+The {{{var(DESCRIPTION)}}} is optional.  If present, it is used as the heading of
+the group.
+
+The {{{var(KEYWORD)}}}-{{{var(VALUE)}}} pairs are optional.  Each keyword has to be a
+keyword symbol, either ~:class~ or a keyword argument supported by the
+constructor of that class.
+
+- One of these keywords, ~:description~, is equivalent to specifying
+  {{{var(DESCRIPTION)}}} at the very beginning of the vector.  The recommendation
+  is to use ~:description~ if some other keyword is also used, for
+  consistency, or {{{var(DESCRIPTION)}}} otherwise, because it looks better.
+
+- Likewise ~:level~ is equivalent to {{{var(LEVEL)}}}.
+
+- Other important keywords include the ~:if...~ and ~:inapt-if...~
+  keywords.  These keywords control whether the group is available
+  in a certain situation.
+
+  For example, one group of the ~magit-rebase~ transient uses ~:if
+  magit-rebase-in-progress-p~, which contains the suffixes that are
+  useful while rebase is already in progress; and another that uses
+  ~:if-not magit-rebase-in-progress-p~, which contains the suffixes that
+  initiate a rebase.
+
+  These predicates can also be used on individual suffixes and are
+  only documented once, see [[*Predicate Slots]].
+
+- The value of ~:hide~, if non-~nil~, is a predicate that controls
+  whether the group is hidden by default.  The key bindings for
+  suffixes of a hidden group should all use the same prefix key.
+  Pressing that prefix key should temporarily show the group and its
+  suffixes, which assumes that a predicate like this is used:
+
+  #+BEGIN_SRC emacs-lisp
+    (lambda ()
+      (eq (car transient--redisplay-key)
+          ?\C-c)) ; the prefix key shared by all bindings
+  #+END_SRC
+
+- The value of ~:setup-children~, if non-~nil~, is a function that takes
+  one argument, a potentially list of children, and must return a list
+  of children or an empty list.  This can either be used to somehow
+  transform the group's children that were defined the normal way, or
+  to dynamically create the children from scratch.
+
+  The returned children must have the same form as stored in the
+  prefix's ~transient--layout~ property, but it is often more convenient
+  to use the same form as understood by ~transient-define-prefix~,
+  described below.  If you use the latter approach, you can use the
+  ~transient-parse-suffixes~ and ~transient-parse-suffix~ functions to
+  transform them from the convenient to the expected form.  Depending
+  on the used group class, ~transient-parse-suffixes~'s SUFFIXES must be
+  a list of group vectors (for ~transient-columns~) or a list of suffix
+  lists (for all other group classes).
+
+  If you explicitly specify children and then transform them using
+  ~:setup-children~, then the class of the group is determined as usual,
+  based on explicitly specified children.
+
+  If you do not explicitly specify children and thus rely solely on
+  ~:setup-children~, then you must specify the class using ~:class~.
+  For backward compatibility, if you fail to do so, ~transient-column~
+  is used and a warning is displayed.  This warning will eventually
+  be replaced with an error.
+
+  #+BEGIN_SRC emacs-lisp
+    (transient-define-prefix my-finder-by-keyword ()
+      "Select a keyword and list matching packages."
+      ;; The real `finder-by-keyword' is more convenient
+      ;; of course, but that is not the point here.
+      [:class transient-columns
+       :setup-children
+       (lambda (_)
+         (transient-parse-suffixes
+          'my-finder-by-keyword
+          (let ((char (1- ?A)))
+            (mapcar                  ; a list ...
+             (lambda (partition)
+               (vconcat              ; of group vectors ...
+                (mapcar (lambda (elt)
+                          (let ((keyword (symbol-name (car elt))))
+                                     ; ... where each suffix is a list
+                            (list (format "%c" (cl-incf char))
+                                  keyword
+                                  (lambda ()
+                                    (interactive)
+                                    (finder-list-matches keyword)))))
+                        partition)))
+             (seq-partition finder-known-keywords 7)))))])
+  #+END_SRC
+
+- The boolean ~:pad-keys~ argument controls whether keys of all suffixes
+  contained in a group are right padded, effectively aligning the
+  descriptions.
+
+- If a keyword argument accepts a function as value, you an use a
+  ~lambda~ expression.  As a special case, the ~##~ macro (which returns a
+  ~lambda~ expression and is implemented in the ~llama~ package) is also
+  supported.  Inside group specifications, the use of ~##~ is not
+  supported anywhere but directly following a keyword symbol.
+
+The {{{var(ELEMENT)}}}s are either all subgroups, or all suffixes and strings.
+(At least currently no group type exists that would allow mixing
+subgroups with commands at the same level, though in principle there
+is nothing that prevents that.)
+
+If the {{{var(ELEMENT)}}}s are not subgroups, then they can be a mixture of
+lists, which specify commands, and strings.  Strings are inserted
+verbatim into the buffer.  The empty string can be used to insert gaps
+between suffixes, which is particularly useful if the suffixes are
+outlined as a table.
+
+Inside group specifications, including inside contained suffix
+specifications, nothing has to be quoted and quoting anyway is
+invalid.  The value following a keyword, can be explicitly unquoted
+using ~,~.  This feature is experimental and should be avoided.
+
+The form of suffix specifications is documented in the next node.
+
+*** Suffix Specifications
+#+cindex: suffix specifications
+
+A transient's suffix and infix commands are bound when the transient
+prefix command is defined using ~transient-define-prefix~, see
+[[*Defining Transients]].  The commands are organized into groups, see
+[[*Group Specifications]].  Here we describe the form used to bind an
+individual suffix command.
+
+The same form is also used when later binding additional commands
+using functions such as ~transient-insert-suffix~, see [[*Modifying
+Existing Transients]].
+
+Note that an infix is a special kind of suffix.  Depending on context
+“suffixes” means “suffixes (including infixes)” or “non-infix
+suffixes”.  Here it means the former.
+
+Suffix specifications have this form:
+
+#+begin_src emacs-lisp
+  ([LEVEL] [KEY [DESCRIPTION]] COMMAND|ARGUMENT [KEYWORD VALUE]...)
+#+end_src
+
+{{{var(LEVEL)}}}, {{{var(KEY)}}} and {{{var(DESCRIPTION)}}} can also be specified using the {{{var(KEYWORD)}}}s
+~:level~, ~:key~ and ~:description~.  If the object that is associated with
+{{{var(COMMAND)}}} sets these properties, then they do not have to be specified
+here.  You can however specify them here anyway, possibly overriding
+the object's values just for the binding inside this transient.
+
+- {{{var(LEVEL)}}} is the suffix level, an integer between 1 and 7.  See
+  [[*Enabling and Disabling Suffixes]].
+
+- {{{var(KEY)}}} is the key binding, either a vector or key description string.
+
+- {{{var(DESCRIPTION)}}} is the description, either a string or a function that
+  takes zero or one arguments (the suffix object) and returns a string.
+  The function should be a lambda expression to avoid ambiguity.  In
+  some cases a symbol that is bound as a function would also work but
+  to be safe you should use ~:description~ in that case.
+
+The next element is either a command or an argument.  This is the only
+argument that is mandatory in all cases.
+
+- {{{var(COMMAND)}}} should be a symbol that is bound as a function, which has
+  to be defined or at least autoloaded as a command by the time the
+  containing prefix command is invoked.
+
+  Any command will do; it does not need to have an object associated
+  with it (as would be the case if ~transient-define-suffix~ or
+  ~transient-define-infix~ were used to define it).
+
+  COMMAND can also be a ~lambda~ expression.
+
+  As mentioned above, the object that is associated with a command can
+  be used to set the default for certain values that otherwise have to
+  be set in the suffix specification.  Therefore if there is no object,
+  then you have to make sure to specify the {{{var(KEY)}}} and the {{{var(DESCRIPTION)}}}.
+
+  As a special case, if you want to add a command that might be neither
+  defined nor autoloaded, you can use a workaround like:
+
+  #+BEGIN_SRC emacs-lisp
+    (transient-insert-suffix 'some-prefix "k"
+      '("!" "Ceci n'est pas une commande" no-command
+        :if (lambda () (featurep 'no-library))))
+  #+END_SRC
+
+  Instead of ~featurep~ you could also use ~require~ with a non-~nil~ value
+  for {{{var(NOERROR)}}}.
+
+- The mandatory argument can also be a command-line argument, a
+  string.  In that case an anonymous command is defined and bound.
+
+  Instead of a string, this can also be a list of two strings, in
+  which case the first string is used as the short argument (which can
+  also be specified using ~:shortarg~) and the second as the long argument
+  (which can also be specified using ~:argument~).
+
+  Only the long argument is displayed in the popup buffer.  See
+  ~transient-detect-key-conflicts~ for how the short argument may be
+  used.
+
+  Unless the class is specified explicitly, the appropriate class is
+  guessed based on the long argument.  If the argument ends with ===
+  (e.g., =--format==) then ~transient-option~ is used, otherwise
+  ~transient-switch~.
+
+Finally, details can be specified using optional {{{var(KEYWORD)}}}-{{{var(VALUE)}}} pairs.
+Each keyword has to be a keyword symbol, either ~:class~ or a keyword
+argument supported by the constructor of that class.  See [[*Suffix
+Slots]].
+
+If a keyword argument accepts a function as value, you an use a ~lambda~
+expression.  As a special case, the ~##~ macro (which returns a ~lambda~
+expression and is implemented in the ~llama~ package) is also supported.
+Inside suffix bindings, the use of ~##~ is not supported anywhere but
+directly following a keyword symbol.
+
+** Defining Suffix and Infix Commands
+#+cindex: defining suffix commands
+#+cindex: defining infix commands
+
+Note that an infix is a special kind of suffix.  Depending on context
+“suffixes” means “suffixes (including infixes)” or “non-infix
+suffixes”.
+
+- Macro: transient-define-suffix name arglist [docstring] [keyword value]... body... ::
+
+  This macro defines {{{var(NAME)}}} as a transient suffix command.
+
+  {{{var(ARGLIST)}}} are the arguments that the command takes.
+  {{{var(DOCSTRING)}}} is the documentation string and is optional.
+
+  These arguments can optionally be followed by keyword-value pairs.
+  Each keyword has to be a keyword symbol, either ~:class~ or a keyword
+  argument supported by the constructor of that class.  The
+  ~transient-suffix~ class is used if the class is not specified
+  explicitly.
+
+  The {{{var(BODY)}}} must begin with an ~interactive~ form that matches {{{var(ARGLIST)}}}.
+  The infix arguments are usually accessed by using ~transient-args~
+  inside ~interactive~.
+
+- Macro: transient-define-infix name arglist [docstring] [keyword value]... ::
+
+  This macro defines {{{var(NAME)}}} as a transient infix command.
+
+  {{{var(ARGLIST)}}} is always ignored (but mandatory never-the-less) and
+  reserved for future use.  {{{var(DOCSTRING)}}} is the documentation string and
+  is optional.
+
+  At least one key-value pair is required.  All transient infix
+  commands are ~equal~ to each other (but not ~eq~).  It is meaningless
+  to define an infix command, without providing at least one keyword
+  argument (usually ~:argument~ or ~:variable~, depending on the class).
+  The suffix class defaults to ~transient-switch~ and can be set using
+  the ~:class~ keyword.
+
+  The function definition is always:
+
+  #+BEGIN_SRC emacs-lisp
+    (lambda ()
+      (interactive)
+      (let ((obj (transient-suffix-object)))
+        (transient-infix-set obj (transient-infix-read obj)))
+      (transient--show))
+  #+END_SRC
+
+  ~transient-infix-read~ and ~transient-infix-set~ are generic functions.
+  Different infix commands behave differently because the concrete
+  methods are different for different infix command classes.  In rare
+  cases the above command function might not be suitable, even if you
+  define your own infix command class.  In that case you have to use
+  ~transient-define-suffix~ to define the infix command and use ~t~ as the
+  value of the ~:transient~ keyword.
+
+- Macro: transient-define-argument name arglist [docstring] [keyword value]... ::
+
+  This macro defines {{{var(NAME)}}} as a transient infix command.
+
+  This is an alias for ~transient-define-infix~.  Only use this alias
+  to define an infix command that actually sets an infix argument.
+  To define an infix command that, for example, sets a variable, use
+  ~transient-define-infix~ instead.
+
+** Using Infix Arguments
+
+The functions and the variables described below allow suffix commands
+to access the value of the transient from which they were invoked;
+which is the value of its infix arguments.  These variables are set
+when the user invokes a suffix command that exits the transient, but
+before actually calling the command.
+
+When returning to the command-loop after calling the suffix command,
+the arguments are reset to ~nil~ (which causes the function to return
+~nil~ too).
+
+Like for Emacs's prefix arguments, it is advisable, but not mandatory,
+to access the infix arguments inside the command's ~interactive~ form.
+The preferred way of doing that is to call the ~transient-args~
+function, which for infix arguments serves about the same purpose as
+~prefix-arg~ serves for prefix arguments.
+
+- Function: transient-args prefix ::
+
+  This function returns the value of the transient prefix command
+  {{{var(PREFIX)}}}.
+
+  If the current command was invoked from the transient prefix command
+  {{{var(PREFIX)}}}, then it returns the active infix arguments.  If the current
+  command was not invoked from {{{var(PREFIX)}}}, then it returns the set, saved
+  or default value for {{{var(PREFIX)}}}.
+
+- Function: transient-get-value ::
+
+  This function returns the value of the current prefix.
+
+  This is mostly intended for internal use, but may also be of use
+  in ~transient-set-value~ and ~transient-save-value~ methods.  Unlike
+  ~transient-args~, this does not include the values of suffixes whose
+  ~unsavable~ slot is non-~nil~.
+
+- Function: transient-arg-value arg args ::
+
+  This function returns the value of {{{var(ARG)}}} as it appears in {{{var(ARGS)}}}.
+
+  For a switch a boolean is returned.  For an option the value is
+  returned as a string, using the empty string for the empty value,
+  or ~nil~ if the option does not appear in {{{var(ARGS)}}}.
+
+- Function: transient-suffixes prefix ::
+
+  This function returns the suffixes of the transient prefix command
+  {{{var(PREFIX)}}}.  This is a list of objects.  This function should only be
+  used if you need the objects (as opposed to just their values) and
+  if the current command is not being invoked from {{{var(PREFIX)}}}.
+
+** Using Prefix Scope
+
+Some transients have a sort of secondary value, called a scope.  A
+prefix's scope can be accessed using ~transient-scope~; similar to how
+its value can be accessed using ~transient-args~.
+
+- Function: transient-scope prefixes classes ::
+
+  This function returns the scope of the active or current transient
+  prefix command.
+
+  If optional PREFIXES and CLASSES are both nil, return the scope of
+  the prefix currently being setup, making this variation useful, e.g.,
+  in ~:if*~ predicates.  If no prefix is being setup, but the current
+  command was invoked from some prefix, then return the scope of that.
+
+  If PREFIXES is non-nil, it must be a prefix command or a list of such
+  commands.  If CLASSES is non-nil, it must be a prefix class or a list
+  of such classes.  When this function is called from the body or the
+  ~interactive~ form of a suffix command, PREFIXES and/or CLASSES should
+  be non-nil.  If either is non-nil, try the following in order:
+
+  - If the current suffix command was invoked from a prefix, which
+    appears in PREFIXES, return the scope of that prefix.
+
+  - If the current suffix command was invoked from a prefix, and its
+    class derives from one of the CLASSES, return the scope of that
+    prefix.
+
+  - If a prefix is being setup and it appears in PREFIXES, return its
+    scope.
+
+  - If a prefix is being setup and its class derives from one of the
+    CLASSES, return its scope.
+
+  - Finally try to return the default scope of the first command in
+    PREFIXES.  This only works if that slot is set in the respective
+    class definition or using its `transient-init-scope' method.
+
+  If no prefix matches, return nil.
+
+** Current Suffix Command
+
+- Function: transient-suffix-object command ::
+
+  This function returns the object associated with the current suffix
+  command.
+
+  Each suffix commands is associated with an object, which holds
+  additional information about the suffix, such as its value (in
+  the case of an infix command, which is a kind of suffix command).
+
+  This function is intended to be called by infix commands, which
+  are usually aliases of ~transient--default-infix-command~, which
+  is defined like this:
+
+  #+begin_src emacs-lisp
+    (defun transient--default-infix-command ()
+      (interactive)
+      (let ((obj (transient-suffix-object)))
+        (transient-infix-set obj (transient-infix-read obj)))
+      (transient--show))
+  #+end_src
+
+  (User input is read outside of ~interactive~ to prevent the
+  command from being added to ~command-history~.)
+
+  Such commands need to be able to access their associated object
+  to guide how ~transient-infix-read~ reads the new value and to
+  store the read value.  Other suffix commands (including non-infix
+  commands) may also need the object to guide their behavior.
+
+  This function attempts to return the object associated with the
+  current suffix command even if the suffix command was not invoked
+  from a transient.  (For some suffix command that is a valid thing
+  to do, for others it is not.)  In that case ~nil~ may be returned,
+  if the command was not defined using one of the macros intended
+  to define such commands.
+
+  The optional argument COMMAND is intended for internal use.  If
+  you are contemplating using it in your own code, then you should
+  probably use this instead:
+
+  #+begin_src emacs-lisp
+    (get COMMAND 'transient--suffix)
+  #+end_src
+
+- Variable: transient-current-suffixes ::
+
+  The suffixes of the transient from which this suffix command was
+  invoked.  This is a list of objects.  Usually it is sufficient to
+  instead use the function ~transient-args~, which returns a list of
+  values.  In complex cases it might be necessary to use this variable
+  instead, i.e., if you need access to information beside the value.
+
+** Current Prefix Command
+
+- Function: transient-prefix-object ::
+
+  This function returns the current prefix as an object.
+
+  While a transient is being setup or refreshed (which involves
+  preparing its suffixes) the variable ~transient--prefix~ can be
+  used to access the prefix object.  Thus this is what has to be
+  used in suffix methods such as ~transient-format-description~,
+  and in object-specific functions that are stored in suffix slots
+  such as ~description~.
+
+  When a suffix command is invoked (i.e., in its ~interactive~ form
+  and function body) then the variable ~transient-current-prefix~
+  has to be used instead.
+
+  Two distinct variables are needed, because any prefix may itself
+  be used as a suffix of another prefix, and such sub-prefixes have
+  to be able to tell themselves apart from the prefix they were
+  invoked from.
+
+  Regular suffix commands, which are not prefixes, do not have to
+  concern themselves with this distinction, so they can use this
+  function instead.  In the context of a plain suffix, it always
+  returns the value of the appropriate variable.
+
+- Variable: transient-current-prefix ::
+
+  The transient from which this suffix command was invoked.  The value
+  is a ~transient-prefix~ object, which holds information associated
+  with the transient prefix command.
+
+- Variable: transient-current-command ::
+
+  The transient from which this suffix command was invoked.  The value
+  is a symbol, the transient prefix command.
+
+- Function: transient-active-prefix &optional prefixes ::
+
+  This function returns the active transient object.  It returns ~nil~
+  if there is no active transient, if the transient buffer isn't
+  shown, and while the active transient is suspended (e.g., while the
+  minibuffer is in use).
+
+  Unlike ~transient-current-prefix~, which is only ever non-~nil~ in code
+  that is run directly by a command that is invoked while a transient
+  is current, this function is also suitable for use in asynchronous
+  code, such as timers and callbacks (this function's main use-case).
+
+  If optional PREFIXES is non-~nil~, it must be a prefix command symbol
+  or a list of symbols, in which case the active transient object is
+  only returned if it matches one of the PREFIXES.
+
+** Transient State
+#+cindex: transient state
+
+Invoking a transient prefix command “activates” the respective
+transient, i.e., it puts a transient keymap into effect, which binds
+the transient's infix and suffix commands.
+
+The default behavior while a transient is active is as follows:
+
+- Invoking an infix command does not affect the transient state; the
+  transient remains active.
+
+- Invoking a (non-infix) suffix command “deactivates” the transient
+  state by removing the transient keymap and performing some
+  additional cleanup.
+
+- Invoking a command that is bound in a keymap other than the
+  transient keymap is disallowed and trying to do so results in a
+  warning.  This does not “deactivate” the transient.
+
+The behavior can be changed for all suffixes of a particular prefix
+and/or for individual suffixes.  The values should nearly always be
+booleans, but certain functions, called “pre-commands”, can also be
+used.  These functions are named ~transient--do-VERB~, and the symbol
+~VERB~ can be used as a shorthand.
+
+A boolean is interpreted as answering the question "does the
+transient stay active, when this command is invoked?"  ~t~ means that
+the transient stays active, while ~nil~ means that invoking the command
+exits the transient.
+
+Note that when the suffix is a “sub-prefix”, invoking that command
+always activates that sub-prefix, causing the outer prefix to no
+longer be active and displayed.  Here ~t~ means that when you exit the
+inner prefix, then the outer prefix becomes active again, while ~nil~
+means that all outer prefixes are exited at once.
+
+- The behavior for non-suffixes can be set for a particular prefix,
+  by the prefix's ~transient-non-suffix~ slot to a boolean, a suitable
+  pre-command function, or a shorthand for such a function.  See
+  [[*Pre-commands for Non-Suffixes]].
+
+- The common behavior for the suffixes of a particular prefix can be
+  set using the prefix's ~transient-suffixes~ slot.
+
+  The value specified in this slot does *not* affect infixes.  Because
+  it affects both regular suffixes as well as sub-prefixes, which
+  have different needs, it is best to avoid explicitly specifying a
+  function.
+
+- The behavior of an individual suffix can be changed using its
+  ~transient~ slot.  While it is usually best to use a boolean, for this
+  slot it can occasionally make sense to specify a function explicitly.
+
+  Note that this slot can be set when defining a suffix command using
+  ~transient-define-suffix~ and/or in the definition of the prefix.  If
+  set in both places, then the latter takes precedence, as usual.
+
+The available pre-command functions are documented in the following
+sub-sections.  They are called by ~transient--pre-command~, a function
+on ~pre-command-hook~, and the value that they return determines whether
+the transient is exited.  To do so the value of one of the constants
+~transient--exit~ or ~transient--stay~ is used (that way we don't have to
+remember if ~t~ means “exit” or “stay”).
+
+Additionally, these functions may change the value of ~this-command~
+(which explains why they have to be called using ~pre-command-hook~),
+call ~transient-export~, ~transient--stack-zap~ or ~transient--stack-push~;
+and set the values of ~transient--exitp~, ~transient--helpp~ or
+~transient--editp~.
+
+For completeness sake, some notes about complications:
+
+- The transient-ness of certain built-in suffix commands is specified
+  using ~transient-predicate-map~.  This is a special keymap, which
+  binds commands to pre-commands (as opposed to keys to commands) and
+  takes precedence over the prefix's ~transient-suffix~ slot, but not
+  the suffix's ~transient~ slot.
+
+- While a sub-prefix is active we nearly always want {{{kbd(C-g)}}} to take the
+  user back to the “super-prefix”, even when the other suffixes don't
+  do that.  However, in rare cases this may not be desirable, in which
+  case ~replace~ can be used as the value of the sub-prefix's ~transient~
+  slot.
+
+*** Pre-commands for Infixes
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+The default for infixes is ~transient--do-stay~.  This is also the only
+function that makes sense for infixes, which is why this predicate is
+used even if the value of the prefix's ~transient-suffix~ slot is ~t~.  In
+extremely rare cases, one might want to use something else, which can
+be done by setting the infix's ~transient~ slot directly.

+
+* Classes and Methods
+#+cindex: classes and methods
+
+Transient uses classes and generic functions to make it possible to
+define new types of suffix and prefix commands, which are similar to
+existing types, but behave differently in some respects.
+
+Every prefix, infix and suffix command is associated with an object,
+which holds information, which controls certain aspects of its
+behavior.  This happens in two ways.
+
+- Associating a command with a certain class gives the command a type.
+  This makes it possible to use generic functions to do certain things
+  that have to be done differently depending on what type of command
+  it acts on.
+
+  That in turn makes it possible for third-parties to add new types
+  without having to convince the maintainer of Transient, that that
+  new type is important enough to justify adding a special case to a
+  dozen or so functions.
+
+- Associating a command with an object makes it possible to easily
+  store information that is specific to that particular command.
+
+  Two commands may have the same type, but obviously their key
+  bindings and descriptions still have to be different, for example.
+
+  The values of some slots are functions.  The ~reader~ slot for example
+  holds a function that is used to read a new value for an infix
+  command.  The values of such slots are regular functions.
+
+  Generic functions are used when a function should do something
+  different based on the type of the command, i.e., when all commands
+  of a certain type should behave the same way but different from the
+  behavior for other types.  Object slots that hold a regular function
+  as value are used when the task that they perform is likely to
+  differ even between different commands of the same type.
+
+** Group Classes
+
+The type of a group can be specified using the ~:class~ property at the
+beginning of the class specification, e.g., ~[:class transient-columns
+...]~ in a call to ~transient-define-prefix~.
+
+- The abstract ~transient-child~ class is the base class of both
+  ~transient-group~ (and therefore all groups) as well as of
+  ~transient-suffix~ (and therefore all suffix and infix commands).
+
+  This class exists because the elements (or “children”) of certain
+  groups can be other groups instead of suffix and infix commands.
+
+- The abstract ~transient-group~ class is the superclass of all other
+  group classes.
+
+- The ~transient-column~ class is the simplest group.
+
+  This is the default “flat” group.  If the class is not specified
+  explicitly and the first element is not a vector (i.e., not a group),
+  then this class is used.
+
+  This class displays each element on a separate line.
+
+- The ~transient-row~ class displays all elements on a single line.
+
+- The ~transient-columns~ class displays commands organized in columns.
+
+  Direct elements have to be groups whose elements have to be commands
+  or strings.  Each subgroup represents a column.  This class takes
+  care of inserting the subgroups' elements.
+
+  This is the default “nested” group.  If the class is not specified
+  explicitly and the first element is a vector (i.e., a group), then
+  this class is used.
+
+- The ~transient-subgroups~ class wraps other groups.
+
+  Direct elements have to be groups whose elements have to be commands
+  or strings.  This group inserts an empty line between subgroups.
+  The subgroups themselves are responsible for displaying their
+  elements.
+
+** Group Methods
+
+- Function: transient-setup-children group children ::
+
+  This generic function can be used to setup the children or a group.
+
+  The default implementation usually just returns the children
+  unchanged, but if the ~setup-children~ slot of {{{var(GROUP)}}} is non-~nil~, then
+  it calls that function with {{{var(CHILDREN)}}} as the only argument and
+  returns the value.
+
+  The children are given as a (potentially empty) list consisting of
+  either group or suffix specifications.  These functions can make
+  arbitrary changes to the children including constructing new
+  children from scratch.
+
+- Function: transient--insert-group group ::
+
+  This generic function formats the group and its elements and inserts
+  the result into the current buffer, which is a temporary buffer.
+  The contents of that buffer are later inserted into the popup buffer.
+
+  Functions that are called by this function may need to operate in
+  the buffer from which the transient was called.  To do so they can
+  temporarily make the ~transient--shadowed-buffer~ the current buffer.
+
+** Prefix Classes
+
+Transient itself provides a single class for prefix commands,
+~transient-prefix~, but package authors may wish to define specialized
+classes.  Doing so makes it possible to change the behavior of the set
+of prefix commands that use that class, by implementing specialized
+methods for certain generic functions (see [[* Prefix Methods]]).
+
+A transient prefix command's object is stored in the ~transient--prefix~
+property of the command symbol.  While a transient is active, a clone
+of that object is stored in the variable ~transient--prefix~.  A clone
+is used because some changes that are made to the active transient's
+object should not affect later invocations.
+
+** Suffix Classes
+
+- All suffix and infix classes derive from ~transient-suffix~, which in
+  turn derives from ~transient-child~, from which ~transient-group~ also
+  derives (see [[*Group Classes]]).
+
+- All infix classes derive from the abstract ~transient-infix~ class,
+  which in turn derives from the ~transient-suffix~ class.
+
+  Infixes are a special type of suffixes.  The primary difference is
+  that infixes always use the ~transient--do-stay~ pre-command, while
+  non-infix suffixes use a variety of pre-commands (see [[*Transient
+  State]]).  Doing that is most easily achieved by using this class,
+  though theoretically it would be possible to define an infix class
+  that does not do so.  If you do that then you get to implement many
+  methods.
+
+  Also, infixes and non-infix suffixes are usually defined using
+  different macros (see [[*Defining Suffix and Infix Commands]]).
+
+- Classes used for infix commands that represent arguments should
+  be derived from the abstract ~transient-argument~ class.
+
+- The ~transient-switch~ class (or a derived class) is used for infix
+  arguments that represent command-line switches (arguments that do
+  not take a value).
+
+- The ~transient-option~ class (or a derived class) is used for infix
+  arguments that represent command-line options (arguments that do
+  take a value).
+
+- The ~transient-switches~ class can be used for a set of mutually
+  exclusive command-line switches.
+
+- The ~transient-files~ class can be used for a =--= argument that
+  indicates that all remaining arguments are files.
+
+- Classes used for infix commands that represent variables should
+  derived from the abstract ~transient-variable~ class.
+
+- The ~transient-information~ and ~transient-information*~ classes are
+  special in that suffixes that use these class are not associated
+  with a command and thus also not with any key binding.  Such
+  suffixes are only used to display arbitrary information, and that
+  anywhere a suffix can appear.  Display-only suffix specifications
+  take these form:
+
+  #+begin_src emacs-lisp
+    ([LEVEL] :info DESCRIPTION [KEYWORD VALUE]...)
+    ([LEVEL] :info* DESCRIPTION [KEYWORD VALUE]...)
+  #+end_src
+
+  The ~:info~ and ~:info*~ keyword arguments replaces the ~:description~
+  keyword used for other suffix classes.  Other keyword arguments that
+  you might want to set, include ~:face~, predicate keywords (such as
+  ~:if~ and ~:inapt-if~), and ~:format~.  By default the value of ~:format~
+  includes ~%k~, which for this class is replaced with the empty string
+  or spaces, if keys are being padded in the containing group.
+
+  The only difference between these two classes is that ~:info*~ aligns
+  its description with the descriptions of suffix commands, while for
+  ~:info~ the description bleeds into the area where suffixes display
+  their key bindings.
+
+- The ~transient-lisp-variable~ class can be used to show and change the
+  value of lisp variables.  This class is not fully featured yet and
+  it is somewhat likely that future improvements won't be fully
+  backward compatible.
+
+- The ~transient-describe-target~ class is used by the command
+  ~transient-describe~.
+
+- The ~transient-value-preset~ class is used to implement the command
+  ~transient-preset~, which activates a value preset.
+
+Magit defines additional classes, which can serve as examples for the
+fancy things you can do without modifying Transient.  Some of these
+classes will likely get generalized and added to Transient.  For now
+they are very much subject to change and not documented.
+
+** Prefix Methods
+
+To get information about the methods implementing these generic
+functions use ~describe-function~.
+
+- Function: transient-init-value obj ::
+
+  This generic function sets the initial value of the object {{{var(OBJ)}}}.
+  Methods exist for both prefix and suffix objects.
+
+  The default method for prefix objects sets the value of OBJ's ~value~
+  slot to the set, saved or default value.  The value that is set for
+  the current session is preferred over the saved value, which is
+  preferred over the default value.
+
+  The default value is determined using the generic function
+  ~transient-default-value~.  If you need to change how the value for a
+  prefix class is determined, its usually sufficient to implement a
+  method for that function.
+
+- Function: transient-default-value obj ::
+
+  This generic function returns the default value of the object {{{var(OBJ)}}}.
+  Methods exist for both prefix and suffix objects.
+
+  The default method for prefix objects returns the value of the
+  ~default-value~ slot if that is bound and not a function.  If it is a
+  function, that is called to get the value.  If the slot is unbound,
+  ~nil~ is returned.
+
+- Function: transient-prefix-value obj ::
+
+  This generic function returns the value of the prefix object {{{var(OBJ)}}}.
+  The respective generic function for infix and suffix objects is
+  named ~transient-infix-value~.
+
+- Function: transient-init-scope obj ::
+
+  This generic function sets the scope of the object {{{var(OBJ)}}}.  Methods
+  exist for both prefix and suffix objects.
+
+  This function is called for all prefix and suffix commands, but
+  unless a concrete method is implemented this falls through to
+  the default implementation, which is a noop.
+
+~transient-set-value~, ~transient-save-value~, ~transient-reset-value~,
+~transient--history-key~, ~transient--history-push~ and
+~transient--history-init~ are other generic functions dealing with the
+value of prefix objects.  See their doc-strings for more information.
+
+~transient-show-help~ is another generic function implemented for prefix
+commands.  The default method effectively describes the command using
+~describe-function~.
+
+** Suffix Methods
+
+To get information about the methods implementing these generic
+functions use ~describe-function~.
+
+*** Suffix Value Methods
+
+- Function: transient-init-value obj ::
+
+  This generic function sets the initial value of the object {{{var(OBJ)}}}.
+  Methods exist for both prefix and suffix objects.
+
+  For ~transient-argument~ objects this function handles setting the
+  value by itself.
+
+  For other ~transient-suffix~ objects (including ~transient-infix~
+  objects), this calls ~transient-default-value~ and uses the value
+  returned by that, unless it is the special value ~eieio--unbound~,
+  which indicates that there is no default value.  Since that is what
+  the default method for ~transient-suffix~ objects does, both of these
+  functions effectively are noops for these classes.
+
+  If you implement a class that derives from ~transient-infix~ directly,
+  then you must implement a dedicated method for this function and/or
+  ~transient-default-value~.
+
+- Function: transient-default-value obj ::
+
+  This generic function returns the default value of the object {{{var(OBJ)}}}.
+  Methods exist for both prefix and suffix objects.
+
+- Function: transient-infix-read obj ::
+
+  This generic function determines the new value of the infix object
+  {{{var(OBJ)}}}.
+
+  This function merely determines the value; ~transient-infix-set~ is
+  used to actually store the new value in the object.
+
+  For most infix classes this is done by reading a value from the
+  user using the reader specified by the ~reader~ slot (using the
+  ~transient-infix-value~ method described below).
+
+  For some infix classes the value is changed without reading
+  anything in the minibuffer, i.e., the mere act of invoking the
+  infix command determines what the new value should be, based
+  on the previous value.
+
+- Function: transient-prompt obj ::
+
+  This generic function returns the prompt to be used to read infix
+  object {{{var(OBJ)}}}'s value.
+
+- Function: transient-infix-set obj value ::
+
+  This generic function sets the value of infix object {{{var(OBJ)}}} to {{{var(VALUE)}}}.
+
+- Function: transient-infix-value obj ::
+
+  This generic function returns the value of the suffix object {{{var(OBJ)}}}.
+
+  This function is called by ~transient-args~ (which see), meaning this
+  function is how the value of a transient is determined so that the
+  invoked suffix command can use it.
+
+  Currently most values are strings, but that is not set in stone.
+  ~nil~ is not a value, it means “no value”.
+
+  Usually only infixes have a value, but see the method for
+  ~transient-suffix~.
+
+- Function: transient-init-scope obj ::
+
+  This generic function sets the scope of the object {{{var(OBJ)}}}.  Methods
+  exist for both prefix and suffix objects.
+
+  The scope is actually a property of the transient prefix, not of
+  individual suffixes.  However it is possible to invoke a suffix
+  command directly instead of from a transient.  In that case, if
+  the suffix expects a scope, then it has to determine that itself
+  and store it in its ~scope~ slot.
+
+  This function is called for all prefix and suffix commands, but
+  unless a concrete method is implemented, this falls through to
+  the default implementation, which is a noop.
+
+*** Suffix Format Methods
+
+# Low-level transient--init-suffix-key intentionally left out.
+
+- Function: transient-format obj ::
+
+  This generic function formats and returns {{{var(OBJ)}}} for display.
+
+  When this function is called, then the current buffer is some
+  temporary buffer.  If you need the buffer from which the prefix
+  command was invoked to be current, then do so by temporarily
+  making ~transient--source-buffer~ current.
+
+- Function: transient-format-key obj ::
+
+  This generic function formats {{{var(OBJ)}}}'s ~key~ for display and returns the
+  result.
+
+- Function: transient-format-description obj ::
+
+  This generic function formats {{{var(OBJ)}}}'s ~description~ for display and
+  returns the result.
+
+- Function: transient-format-value obj ::
+
+  This generic function formats {{{var(OBJ)}}}'s value for display and returns
+  the result.
+
+- Function: transient-show-help obj ::
+
+  Show help for the prefix, infix or suffix command represented by
+  {{{var(OBJ)}}}.
+
+  Regardless of OBJ's type, if its ~show-help~ slot is non-~nil~, that
+  must be a function, which takes OBJ is its only argument.  It must
+  prepare, display and return a buffer, and select the window used to
+  display it.  The ~transient-show-help-window~ macro is intended for
+  use in such functions.
+
+  For prefixes, show the info manual, if that is specified using the
+  ~info-manual~ slot.  Otherwise, show the manpage if that is specified
+  using the ~man-page~ slot.  Otherwise, show the command's
+  documentation string.
+
+  For suffixes, show the command's documentation string.
+
+  For infixes, show the manpage if that is specified.  Otherwise show
+  the command's documentation string.
+
+- Macro: transient-with-help-window &rest body ::
+
+  Evaluate BODY, send output to ~*Help*~ buffer, and display it in a
+  window.  Select the help window, and make the help buffer current
+  and return it.
+
+- Function: transient-show-summary obj &optional return ::
+
+  This generic function shows or, if optional RETURN is non-~nil~,
+  returns a brief summary about the command at point or hovered with
+  the mouse.
+
+  This function is called when the mouse is moved over a command and
+  (if the value of ~transient-enable-popup-navigation~ is ~verbose~) when
+  the user navigates to a command using the keyboard.
+
+  If OBJ's ~summary~ slot is a string, that is used.  If ~summary~ is a
+  function, that is called with OBJ as the only argument and the
+  returned string is used.  If ~summary~ is or returns something other
+  than a string or ~nil~, no summary is shown.  If ~summary~ is or returns
+  ~nil~, the first line of the documentation string is used, if any.
+
+  If RETURN is non-~nil~, this function returns the summary instead of
+  showing it.  This is used when a tooltip is needed.
+
+** Prefix Slots
+*** Value and Scope
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+- ~default-value~ The default value of the prefix.  Use the keyword
+  argument ~:value~ (sic) to set this slot in the definition of a
+  prefix.
+
+- ~init-value~ A function that is responsible for setting the object's
+  value.  If bound, then this is called with the object as the only
+  argument.  Usually this is not bound, in which case the object's
+  primary ~transient-init-value~ method is called instead.
+
+- ~history-key~ If multiple prefix commands should share a single value,
+  then this slot has to be set to the same value for all of them.  You
+  probably don't want that.
+
+- ~incompatible~ A list of lists.  Each sub-list specifies a set of
+  mutually exclusive arguments.  Enabling one of these arguments
+  causes the others to be disabled.  An argument may appear in
+  multiple sub-lists.  Arguments must me given in the same form as
+  used in the ~argument~ or ~argument-format~ slot of the respective
+  suffix objects, usually something like ~--switch~ or ~--option=%s~.  For
+  options and ~transient-switches~ suffixes it is also possible to match
+  against a specific value, as returned by ~transient-infix-value~,
+  for example, ~--option=one~.
+
+- ~scope~ For some transients it might be necessary to have a sort of
+  secondary value, called a “scope”.  See ~transient-define-prefix~.
+
+*** Behavior
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+- ~transient-suffix~, ~transient-non-suffix~ and ~transient-switch-frame~
+  play a part when determining whether the currently active transient
+  prefix command remains active/transient when a suffix or arbitrary
+  non-suffix command is invoked.  See [[*Transient State]].
+
+- ~refresh-suffixes~ Normally suffix objects and keymaps are only setup
+  once, when the prefix is invoked.  Setting this to ~t~, causes them to
+  be recreated after every command.  This is useful when using ~:if...~
+  predicates, and those need to be rerun for some reason.  Doing this
+  is somewhat costly, and there is a risk of losing state, so this is
+  disabled by default and still considered experimental.
+
+- ~environment~ A function used to establish an environment while
+  initializing, refreshing or redisplaying a transient prefix menu.
+  This is useful to establish a cache, in case multiple suffixes
+  require the same expensive work.  The provided function is called
+  with at least one argument, the function for which it establishes
+  the environment.  It must ~funcall~ that function with no arguments.
+  During initialization the second argument is the prefix object
+  being initialized.  This slot is still experimental.
+
+*** Appearance
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+- ~display-action~ determines how this prefix is displayed, overriding
+  ~transient-display-buffer-action~.  It should have the same type.
+
+- ~mode-line-format~ is this prefix's mode line format, overriding
+  ~transient-mode-line-format~.  It should have the same type.
+
+- ~column-widths~ is only respected inside ~transient-columns~ groups and
+  allows aligning columns across separate instances of that.  A list
+  of integers.
+
+- ~variable-pitch~ controls whether alignment is done pixel-wise to
+  account for use of variable-pitch characters, which is useful, e.g.,
+  when using emoji.
+
+*** Documentation
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+- ~show-help~, ~man-page~ or ~info-manual~ can be used to specify the
+  documentation for the prefix and its suffixes.  The command
+  ~transient-help~ uses the function ~transient-show-help~ (which see) to
+  lookup and use these values.
+
+- ~suffix-description~ can be used to specify a function which provides
+  fallback descriptions for suffixes that lack a description.  This
+  is intended to be temporarily used when implementing of a new prefix
+  command, at which time ~transient-command-summary-or-name~ is a useful
+  value.
+
+*** Internal
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+These slots are mostly intended for internal use.  They should not be
+set in calls to ~transient-define-prefix~.
+
+- ~prototype~ When a transient prefix command is invoked, then a clone
+  of that object is stored in the global variable ~transient--prefix~
+  and the prototype is stored in the clone's ~prototype~ slot.
+
+- ~command~ The command, a symbol.  Each transient prefix command
+  consists of a command, which is stored in a symbol's function slot
+  and an object, which is stored in the ~transient--prefix~ property
+  of the same symbol.
+
+- ~level~ The level of the prefix commands.  The suffix commands whose
+  layer is equal or lower are displayed.  See [[*Enabling and Disabling
+  Suffixes]].
+
+- ~value~ The likely outdated value of the prefix.  Instead of accessing
+  this slot directly you should use the function ~transient-get-value~,
+  which is guaranteed to return the up-to-date value.
+
+- ~history~ and ~history-pos~ are used to keep track of historic values.
+  Unless you implement your own ~transient-infix-read~ method you should
+  not have to deal with these slots.
+
+- ~unwind-suffix~ is used internally to ensure transient state is
+  properly exited, even in case of an error.
+
+** Suffix Slots
+
+Here we document most of the slots that are only available for suffix
+objects.  Some slots are shared by suffix and group objects, they are
+documented in [[*Predicate Slots]].
+
+Also see [[*Suffix Classes]].
+
+*** Slots of ~transient-child~
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+This is the abstract superclass of ~transient-suffix~ and ~transient-group~.
+This is where the shared ~if*~ and ~inapt-if*~ slots (see [[*Predicate Slots]]),
+the ~level~ slot (see [[*Enabling and Disabling Suffixes]]), and the ~advice~
+and ~advice*~ slots (see [[*Slots of ~transient-suffix~]]) are defined.
+
+- ~parent~ The object for the parent group.
+
+*** Slots of ~transient-suffix~
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+- ~key~ The key, a key vector or a key description string.
+
+- ~command~ The command, a symbol.
+
+- ~transient~ Whether to stay transient.  See [[*Transient State]].
+
+- ~format~ The format used to display the suffix in the popup buffer.
+  It must contain the following %-placeholders:
+
+  - ~%k~ For the key.
+  - ~%d~ For the description.
+  - ~%v~ For the infix value.  Non-infix suffixes don't have a value.
+
+- ~description~ The description, either a string or a function, which is
+  called with zero or one argument (the suffix object), and returns a
+  string.
+
+- ~face~ Face used for the description.  In simple cases it is easier
+  to use this instead of using a function as ~description~ and adding
+  the styling there.  ~face~ is appended using ~add-face-text-property~.
+
+- ~show-help~ A function used to display help for the suffix.  If
+  unspecified, the prefix controls how help is displayed for its
+  suffixes.  See also function ~transient-show-help~.
+
+- ~summary~ The summary displayed in the echo area, or as a tooltip.
+  If this is ~nil~, which it usually should be, the first line of the
+  documentation string is used instead.  See ~transient-show-summary~
+  for details.
+
+- ~definition~ A command, which is used if the body is omitted when
+  defining a command using ~transient-define-suffix~.
+
+The following two slots are experimental.  They can also be set for a
+group, in which case they apply to all suffixes in that group, except
+for suffixes that set the same slot to a non-nil value.
+
+- ~advice~ A function used to advise the command.  The advise is called
+  using ~(apply advice command args)~, i.e., it behaves like an "around"
+  advice.
+
+- ~advice*~ A function used to advise the command.  Unlike ~advice~, this
+  advises not only the command body but also its ~interactive~ spec.  If
+  both slots are non-nil, ~advice~ is used for the body and ~advice*~ is
+  used for the ~interactive~ form.  When advising the ~interactive~ spec,
+  called using ~(funcall advice #'advice-eval-interactive-spec spec)~.
+
+*** Slots of ~transient-infix~
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+Some of these slots are only meaningful for some of the subclasses.
+They are defined here anyway to allow sharing certain methods.
+
+- ~argument~ The long argument, e.g., ~--verbose~.
+
+- ~shortarg~ The short argument, e.g., ~-v~.
+
+- ~value~ The value.  Should not be accessed directly.
+
+- ~init-value~ Function that is responsible for setting the object's
+  value.  If bound, then this is called with the object as the only
+  argument.  Usually this is not bound, in which case the object's
+  primary ~transient-init-value~ method is called instead.
+
+- ~unsavable~ Whether the value of the suffix is not saved as part of
+  the prefixes.
+
+- ~multi-value~ For options, whether the option can have multiple
+  values.  If this is non-~nil~, then the values are read using
+  ~completing-read-multiple~ by default and if you specify your own
+  reader, then it should read the values using that function or
+  similar.
+
+  Supported non-~nil~ values are:
+
+  - Use ~rest~ for an option that can have multiple values.  This is
+    useful e.g., for an ~--~ argument that indicates that all remaining
+    arguments are files (such as ~git log -- file1 file2~).
+
+    In the list returned by ~transient-args~ such an option and its
+    values are represented by a single list of the form ~(ARGUMENT
+    . VALUES)~.
+
+  - Use ~repeat~ for an option that can be specified multiple times.
+
+    In the list returned by ~transient-args~ each instance of the option
+    and its value appears separately in the usual from, for example:
+    ~("--another-argument" "--option=first" "--option=second")~.
+
+  In both cases the option's values have to be specified in the
+  default value of a prefix using the same format as returned by
+  ~transient-args~, e.g., ~("--other" "--o=1" "--o=2" ("--" "f1" "f2"))~.
+
+- ~always-read~ For options, whether to read a value on every invocation.
+  If this is ~nil~, then options that have a value are simply unset and
+  have to be invoked a second time to set a new value.
+
+- ~allow-empty~ For options, whether the empty string is a valid value.
+
+- ~history-key~ The key used to store the history.  This defaults to the
+  command name.  This is useful when multiple infixes should share the
+  same history because their values are of the same kind.
+
+- ~reader~ The function used to read the value of an infix.  Not used
+  for switches.  The function takes three arguments, {{{var(PROMPT)}}},
+  {{{var(INITIAL-INPUT)}}} and {{{var(HISTORY)}}}, and must return a string.
+
+- ~prompt~ The prompt used when reading the value, either a string or a
+  function that takes the object as the only argument and which
+  returns a prompt string.
+
+- ~choices~ A list of valid values, or a function that returns such a
+  list.  The latter is not implemented for ~transient-switches~, because
+  I couldn't think of a use-case.  How exactly the choices are used
+  varies depending on the class of the suffix.
+
+*** Slots of ~transient-variable~
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+- ~variable~ The variable.
+
+*** Slots of ~transient-switches~
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+- ~argument-format~ The display format.  Must contain ~%s~, one of the
+  ~choices~ is substituted for that.  E.g., ~--%s-order~.
+
+- ~argument-regexp~ The regexp used to match any one of the switches.
+  E.g., ~\\(--\\(topo\\|author-date\\|date\\)-order\\)~.
+
+** Predicate Slots
+
+Suffix and group objects share two sets of predicate slots that
+control whether a group or suffix should be available depending on
+some state.  Only one slot from each set can be used at the same
+time.  It is undefined which slot is honored if you use more than
+one.
+
+Predicates from the first group control whether the suffix is present
+in the menu at all.
+
+- ~if~ Enable if predicate returns non-~nil~.
+- ~if-not~ Enable if predicate returns ~nil~.
+- ~if-non-nil~ Enable if variable's value is non-~nil~.
+- ~if-nil~ Enable if variable's value is ~nil~.
+- ~if-mode~ Enable if major-mode matches value.
+- ~if-not-mode~ Enable if major-mode does not match value.
+- ~if-derived~ Enable if major-mode derives from value.
+- ~if-not-derived~ Enable if major-mode does not derive from value.
+
+Predicates from the second group control whether the suffix can be
+invoked.  The suffix is shown in the menu regardless, but when it
+is considered "inapt", then it is grayed out to indicated that it
+currently cannot be invoked.
+
+- ~inapt-if~ Inapt if predicate returns non-~nil~.
+- ~inapt-if-not~ Inapt if predicate returns ~nil~.
+- ~inapt-if-non-nil~ Inapt if variable's value is non-~nil~.
+- ~inapt-if-nil~ Inapt if variable's value is ~nil~.
+- ~inapt-if-mode~ Inapt if major-mode matches value.
+- ~inapt-if-not-mode~ Inapt if major-mode does not match value.
+- ~inapt-if-derived~ Inapt if major-mode derives from value.
+- ~inapt-if-not-derived~ Inapt if major-mode does not derive from value.
+
+By default these predicates run when the prefix command is invoked,
+but this can be changes, using the ~refresh-suffixes~ prefix slot.
+See [[*Prefix Slots]].
+
+One more slot is shared between group and suffix classes, ~level~.  Like
+the slots documented above, it is a predicate, but it is used for a
+different purpose.  The value has to be an integer between 1
+and 7.  ~level~ controls whether a suffix or a group should be

+** Can I control how the popup buffer is displayed?
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+Yes, see ~transient-display-buffer-action~ in [[*Configuration]].  You can
+also control how the popup buffer is displayed on a case-by-case basis
+by passing ~:display-action~ to ~transient-define-prefix~.
+
+** How can I copy text from the popup buffer?
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+To be able to mark text in Transient's popup buffer using the mouse,
+you have to add the below binding.  Note that for technical reasons,
+the region won't be visualized, while doing so.  After you have quit
+the transient popup, you will be able to yank it in another buffer.
+
+#+begin_src emacs-lisp
+  (keymap-set transient-predicate-map
+              "<mouse-set-region>"
+              #'transient--do-stay)
+#+end_src
+
+** How can I autoload prefix and suffix commands?
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+If your package only supports Emacs 30, just prefix the definition
+with ~;;;###autoload~.  If your package supports released versions of
+Emacs, you unfortunately have to use a long form autoload comment
+as described in [[info:elisp#Autoload]].
+
+#+begin_src emacs-lisp
+  ;;;###autoload (autoload 'magit-dispatch "magit" nil t)
+  (transient-define-prefix magit-dispatch ()
+    ...)

+
+** Why did some of the key bindings change?
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+You may have noticed that the bindings for some of the common commands
+do *not* have the prefix {{{kbd(C-x)}}} and that furthermore some of these commands
+are grayed out while others are not.  That unfortunately is a bit
+confusing if the section of common commands is not shown permanently,
+making the following explanation necessary.
+
+The purpose of usually hiding that section but showing it after the
+user pressed the respective prefix key is to conserve space and not
+overwhelm users with too much noise, while allowing the user to
+quickly list common bindings on demand.
+
+That however should not keep us from using the best possible key
+bindings.  The bindings that do use a prefix do so to avoid wasting
+too many non-prefix bindings, keeping them available for use in
+individual transients.  The bindings that do not use a prefix and that
+are *not* grayed out are very important bindings that are *always*
+available, even when invoking the “common command key prefix” or *any
+other* transient-specific prefix.  The non-prefix keys that *are* grayed
+out however, are not available when any incomplete prefix key sequence
+is active.  They do not use the “common command key prefix” because it
+is likely that users want to invoke them several times in a row and
+e.g., {{{kbd(M-p M-p M-p)}}} is much more convenient than {{{kbd(C-x M-p C-x M-p C-x M-p)}}}.
+
+You may also have noticed that the “Set” command is bound to {{{kbd(C-x s)}}},
+while Magit-Popup used to bind {{{kbd(C-c C-c)}}} instead.  I have seen several
+users praise the latter binding (sic), so I did not change it
+willy-nilly.  The reason that I changed it is that using different
+prefix keys for different common commands, would have made the
+temporary display of the common commands even more confusing, i.e.,
+after pressing {{{kbd(C-c)}}} all the bindings that begin with the {{{kbd(C-x)}}} prefix
+would be grayed out.
+
+Using a single prefix for common commands key means that all other
+potential prefix keys can be used for transient-specific commands
+*without* the section of common commands also popping up.  {{{kbd(C-c)}}} in
+particular is a prefix that I want to (and already do) use for Magit, and
+also using that for a common command would prevent me from doing so.
+
+(See also the next question.)
+
+** Why does {{{kbd(q)}}} not quit popups anymore?
+:PROPERTIES:
+:UNNUMBERED: notoc
+:END:
+
+I agree that {{{kbd(q)}}} is a good binding for commands that quit something.
+This includes quitting whatever transient is currently active, but it
+also includes quitting whatever it is that some specific transient is
+controlling.  The transient ~magit-blame~ for example binds {{{kbd(q)}}} to the
+command that turns ~magit-blame-mode~ off.
+
+So I had to decide if {{{kbd(q)}}} should quit the active transient (like
+Magit-Popup used to) or whether {{{kbd(C-g)}}} should do that instead, so that {{{kbd(q)}}}
+could be bound in individual transient to whatever commands make sense
+for them.  Because all other letters are already reserved for use by
+individual transients, I have decided to no longer make an exception
+for {{{kbd(q)}}}.
+
+If you want to get {{{kbd(q)}}}'s old binding back then you can do so.  Doing
+that is a bit more complicated than changing a single key binding, so
+I have implemented a function, ~transient-bind-q-to-quit~ that makes the
+necessary changes.  See its documentation string for more information.
