;;; Commentary:
|
||
|
|
|
||
|
|
;; This mode teaches you to use the proper Emacs movement keys in a
|
||
|
|
;; rather harsh manner.
|
||
|
|
|
||
|
|
;; No-easy-keys disables arrow, end, home and delete keys, as well as
|
||
|
|
;; their control and meta prefixes. When using any of these keys, you
|
||
|
|
;; instead get a message informing you of the proper Emacs shortcut
|
||
|
|
;; you should use instead (e.g. pressing down informs you to use C-n).
|
||
|
|
|
||
|
|
;; The easy keys are not disabled in the minibuffer. The minibuffer
|
||
|
|
;; has different proper keys replacements than regular buffers and
|
||
|
|
;; depending on various extensions such as icicles, ido, etc.
|
||
|
|
|
||
|
|
;; To install, save no-easy-keys.el in your load path and add the
|
||
|
|
;; following to your .emacs file:
|
||
|
|
;;
|
||
|
|
;; (require 'no-easy-keys)
|
||
|
|
;; (no-easy-keys 1)
|
||
|
|
|
||
|
|
;; You can toggle no-easy-keys using 'M-x no-easy-keys'.
