My finger tends to linger on the Ctrl key and I happen to hit C-RET quite often. I also use cua-mode which binds this to cua-clear-rectangle-mark. I don't want C-RET bound to anything while in this mode.

I can't seem to unbind it though. I've tried:

(global-unset-key (kbd "C-RET"))
(global-unset-key (kbd "<C-return>"))
(global-unset-key [(control return)])
(define-key global-map (kbd "C-RET") 'ignore)
(define-key global-map (kbd "<C-return>") 'ignore)
(define-key global-map [(control return)] 'ignore)

I also tried the following in my .inputrc with no success:

"\C-RET": "\n"

There also doesn't seem to be a cua-mode-map:

;; Doesn't work
(define-key cua-mode-map "C-RET" nil)
  • (define-key cua-mode-map (kbd "C-<return>") nil) (define-key cua-mode-map (kbd "C-RET") nil) ? – PythonNut Aug 6 '15 at 0:53
  • There is no cua-mode-map. At least not in 24.5.1. – Zhro Aug 6 '15 at 1:01

In Emacs 25, if you run C-h k C-RET it will tell you that C-RET is bound in cua-global-keymap, so that's where we unset it

(define-key cua-global-keymap [C-return] nil)

It seems to be set in the same keymap in 24.4 as well.

  • I've loaded emacs with -q and don't see cua-global-keymap listed anywhere when invoking C-h k C-RET while in cua-mode. – Zhro Aug 6 '15 at 1:19
  • With emacs -q cua-mode doesn't get loaded. Does the keymap exist after you do M-x cua-mode? – erikstokes Aug 6 '15 at 1:21
  • I explicitly enable cua-mode after loading emacs with -q in this instance. I'm sorry I wasn't clear enough on that. – Zhro Aug 6 '15 at 1:25
  • @erikstokes The keymap information in C-h k was introduced only recently in the dev version of emacs on its git master. Are you building your emacs from git? – Kaushal Modi Aug 6 '15 at 1:30
  • @Zhro The old school method of grepping in emacs source code always works :) – Kaushal Modi Aug 6 '15 at 1:31
