Emacs: Define Key Sequence

By Xah Lee. Date: . Last updated: .

In emacs, you can define key sequences.

Suppose you want:

  ;; define a prefix keymap
  (define-prefix-command 'my-f9-key-map)
  (define-key my-xyz-map (kbd "<f6>") 'visual-line-mode)
  (define-key my-xyz-map (kbd "<f7>") 'whitespace-mode)
  (define-key my-xyz-map (kbd "<f8>") 'toggle-frame-fullscreen)

(global-set-key (kbd "<f9>") my-f9-key-map)

;; now, 【F9 F6】 will call visual-line-mode

Press the lead key, then you can press 【Ctrl+h】 to see all available key/commands that follows.

Why is Key Sequence Useful

You can add other commands you use, for example:

(info "(elisp) Keymaps")
