如何将Mx映射到emacs 24中的“`”键（Mac OS X Lion）

Question

I've downloaded Emacs 24 pretest for Mac OS X and using Prelude + evil kit. I am coming from vim background and find that Mx is too slow and painful to use. Is there any way to map Mx key to ` key that is near the ESC key? Thanks.

Answer 1

(global-set-key (kbd "`") 'execute-extended-command)

Answer 2

find that Mx is too slow and painful to use

I'm a touch-typist and I happen to think the same and I also think that, in addition, all the Cx shortcuts are very hard to do too.

Is there any way to map Mx key to ` key that is near the ESC key?

I would say that the ESC key is not really a "close" key: your left pinky has to travel a lot to get there (you either need to move your entire hand, which is not efficient, or you need to "stretch" your fingers).

What I did, on a QWERTY keyboard, is to remap CX to C-,

You may want to do something similar: in my opinion it really helps. So maybe mapping Cx to C-, and Mx to M-, would help?

You can do this like the other answer suggested by directly setting a global key:

(define-key global-map [(control ,)] ctl-x-map)

or you can define your own minor-mode where you put all your mappings and then turn that minor mode on (I learned that here on SO):

(define-key my-keys-minor-mode-map (kbd "C-,") ctl-x-map)
(define-key my-keys-minor-mode-map (kbd "M-,") 'execute-extended-command)
... put more mappings here ...

(define-minor-mode my-keys-minor-mode
  "A minor mode so that my key settings override annoying major modes."
  t " my-keys" 'my-keys-minor-mode-map)

(my-keys-minor-mode 1)

Or course you "lose" the previous mappings to C-, and M-, but IMHO it's totally worth it.

You probably want to read user scottfrazer 's great answer and explanation here (that's what I followed to create my own key minor-mode in my .emacs file):
