I've switched from emacs to spacemacs, but my muscle memory still uses the standard emacs keybindings -- despite attempts at avoiding key chords. As an example, to save a file, I continue to use Ctrl x s instead of SPC f s.

What I'd like is a function that would provide a modeline prompt for keystrokes that I'm trying to avoid.

"Ctrl x s deprecated. Use instead: SPC f s"


Update: I used the function that muffinmad supplied with a minor tweak. For some tasks my attention isn't focused on the modeline, so an additional audio alert helps:

    (play-sound-file "oops.wav")

Well...

(global-set-key (kbd "C-x C-s") (lambda ()
                                  (interactive)
                                  (message "Ctrl x s deprecated. Use instead: SPC f s")))

save-buffer may be called while displaying deprecation message but doing so will reduce effectiveness. Just displaying deprecation message will force you to use new key binding.

  • Can you elaborate? Shouldn't this function try to execute whatever it was supposed to be bound to while displaying the deprecation warning? – DoMiNeLa10 May 22 at 7:10
