Each +state has a *global keymap*, where the default bindings for that state +are stored. They are named ``evil-normal-state-map``, +``evil-insert-state-map``, and so on. The bindings in these maps are +visible in all buffers currently in the corresponding state. + +These keymaps function like ordinary Emacs keymaps and may be modified +using the Emacs function ``define-key``: + +.. code-block:: elisp + + (define-key evil-normal-state-map (kbd "w") 'some-function) + +This binds the key :kbd:`w` to the command ``some-function`` in normal +state. The use of ``kbd`` is optional for simple key sequences, like +this one, but recommended in general. + +Most of Evil's bindings are defined in the file ``evil-maps.el``. + +To facilitate shared keybindings between states, some states may +activate keybindings from other states as well. For example, motion +state bindings are visible in normal and visual state, and normal +state bindings are also visible in visual state. + +Each state also has a *buffer-local keymap* which is specific to the +current buffer, and which takes precedence over the global keymap. +These maps are most suitably modified by a mode hook. They are named +``evil-normal-state-local-map``, ``evil-insert-state-local-map``, and +so on. + +.. code-block:: elisp + + (add-hook 'some-mode-hook + (lambda () + (define-key evil-normal-state-local-map + (kbd "w") 'some-function))) + +For convenience, the functions :elisp:ref:`evil-global-set-key` and +:elisp:ref:`evil-local-set-key` are available for setting global and +local state keys. + +.. elisp:autofunction:: evil-global-set-key + +.. elisp:autofunction:: evil-local-set-key + +The above examples could therefore have been written as follows: + +.. code-block:: elisp + + (evil-global-set-key 'normal (kbd "w") 'some-function) + + (add-hook 'some-mode-hook + (lambda () + (evil-local-set-key 'normal (kbd "w") 'some-function))) + + +evil-define-key +--------------- + +Evil provides the macro :elisp:ref:`evil-define-key` for adding state +bindings to ordinary keymaps. It is quite powerful, and is the +preferred method for fine-tuning bindings to activate in specific +circumstances. + +.. elisp:autofunction:: evil-define-key + +There follows a brief overview of the main functions of this macro. + +- Define a binding in a given state + + .. code-block:: elisp + + (evil-define-key 'state 'global (kbd "key") 'target) + +- Define a binding in a given state in the current buffer + + .. code-block:: elisp + + (evil-define-key 'state 'local (kbd "key") 'target) + +- Define a binding in a given state under the *foo-mode* major mode. + + .. code-block:: elisp + + (evil-define-key 'state foo-mode-map (kbd "key") 'target) + + Note that ``foo-mode-map`` is unquoted, and that this form is safe + before ``foo-mode-map`` is loaded. + +- Define a binding in a given state under the *bar-mode* minor mode. + + .. code-block:: elisp + + (evil-define-key 'state 'bar-mode (kbd "key") 'target) + + Note that ``bar-mode`` is quoted, and that this form is safe before + ``bar-mode`` is loaded. + + +The macro :elisp:ref:`evil-define-key` can be used to augment existing +modes with state bindings, as well as creating packages with custom +bindings. For example, the following will create a minor mode +``foo-mode`` with normal state bindings for the keys :kbd:`w` and +:kbd:`e`: + +.. code-block:: elisp + + (define-minor-mode foo-mode + "Foo mode." + :keymap (make-sparse-keymap)) + + (evil-define-key 'normal 'foo-mode "w" 'bar) + (evil-define-key 'normal 'foo-mode "e" 'baz) + +This minor mode can then be enabled in any buffers where the custom +bindings are desired: + +.. code-block:: elisp + + (add-hook 'text-mode-hook 'foo-mode) ; enable alongside text-mode + + +Leader keys +----------- + +Evil supports a simple implementation of Vim's *leader* keys. To bind +a function to a leader key you can use the expression ``<leader>`` in +a key mapping, e.g. + +.. code-block:: elisp + + (evil-define-key 'normal 'global (kbd "<leader>fs") 'save-buffer) + +Likewise, you can use the expression ``<localleader>`` to mimic Vim's +local leader, which is designed for mode-specific key bindings. + +You can use the function :elisp:ref:`evil-set-leader` to designate +which key acts as the leader and the local leader. + +.. elisp:autofunction:: evil-set-leader |
