Disabling prefix key binding

Question

In shell mode on emacs, the current key binding for quitting the shell mode ('comint-interrupt-subjob) is "\C-c \C-c", and I want to change it to "\C-c" as in ordinary linux shell. I tried

(add-hook 'shell-mode-hook '(lambda ()
  (local-set-key "\C-c" 'comint-interrupt-subjob)
))

But it did not work. Probably I need to disable the prefix assigned to "\C-c". How can I do that?

Answer 1

Try this:

(eval-after-load "shell"
  '(define-key shell-mode-map (kbd "C-c") 'comint-interrupt-subjob))

In general, when you define keys you should define them in particular keymaps, as opposed to just hoping the local-set-key does what you want.

Note: I prefer using kbd for describing keys, your "\C-c" would work just fine.

Answer 2

(define-key (current-local-map) "^C" 'comint-interrupt-subjob)

This will do the work without the error checking of local-set-key
