This module aims to solve that ;; problem. ;; ;; Bind keys as follows in your .emacs: ;; ;; (require 'bind-key) ;; ;; (bind-key "C-c x" 'my-ctrl-c-x-command) ;; ;; If you want the keybinding to override all minor modes that may also bind ;; the same key, use the `bind-key*' form: ;; ;; (bind-key* "" 'other-window) ;; ;; If you want to rebind a key only in a particular keymap, use: ;; ;; (bind-key "C-c x" 'my-ctrl-c-x-command some-other-mode-map) ;; ;; To unbind a key within a keymap (for example, to stop your favorite major ;; mode from changing a binding that you don't want to override everywhere), ;; use `unbind-key': ;; ;; (unbind-key "C-c x" some-other-mode-map) ;; ;; To bind multiple keys at once, or set up a prefix map, a `bind-keys' macro ;; is provided. It accepts keyword arguments, please see its documentation ;; for a detailed description. ;; ;; To add keys into a specific map, use :map argument ;; ;; (bind-keys :map dired-mode-map ;; ("o" . dired-omit-mode) ;; ("a" . some-custom-dired-function)) ;; ;; To set up a prefix map, use `:prefix-map' and `:prefix' arguments (both are ;; required) ;; ;; (bind-keys :prefix-map my-customize-prefix-map ;; :prefix "C-c c" ;; ("f" . customize-face) ;; ("v" . customize-variable)) ;; ;; You can combine all the keywords together. Additionally, ;; `:prefix-docstring' can be specified to set documentation of created ;; `:prefix-map' variable. ;; ;; To bind multiple keys in a `bind-key*' way (to be sure that your bindings ;; will not be overridden by other modes), you may use `bind-keys*' macro: ;; ;; (bind-keys* ;; ("C-o" . other-window) ;; ("C-M-n" . forward-page) ;; ("C-M-p" . backward-page)) ;; ;; After Emacs loads, you can see a summary of all your personal keybindings ;; currently in effect with this command: ;; ;; M-x describe-personal-keybindings ;; ;; This display will tell you if you've overriden a default keybinding, and ;; what the default was. Also, it will tell you if the key was rebound after ;; your binding it with `bind-key', and what it was rebound it to.
