Swap Keys

Here's how to swap keys.

put this in your Emacs Init File:

;; swap keys
(define-key key-translation-map (kbd "<f11>") (kbd "<f12>"))
(define-key key-translation-map (kbd "<f12>") (kbd "<f11>"))
(define-key key-translation-map [?\M-x] [?\M-t])
(define-key key-translation-map [?\M-t] [?\M-x])

keyboard-translate

Note: there's the function keyboard-translate. However, it is designed to translate character only.

So, key combination isn't a character and you can't use it for Emacs Keys: Super Hyper key combination.

(Due to historical reasons, keyboard-translate does work for some Ctrl combination key. )
