Restoring Old Key Binding for eval-expression

Restoring Old Key Binding for eval-expression

[rwgpost]

I am just starting to use a current version of Emacs that has eval-expression bound to M-:.  I used to use eval-expression a lot and loved being able to just type Esc Esc to invoke eval-expression.  Is there a way to restore this in my .emacs file?  I've tried several things, like:

 (global-set-key "\M-ESC" 'eval-expression)
 (global-set-key "\M-ESC" 'eval-expression)
 (global-set-key "ESC-ESC" 'eval-expression)

but I can't get any of these to work.  M-: is unwieldy as I have to hit the Meta key, the colon, and the shift key all at the same time.

I really miss Esc Esc, which used to work I guess because the old binding was M-Esc, and Esc-Esc did the same thing.

I've tried googling for help on this but am having trouble finding anything.  When I google "emacs restore m-esc eval-expression' I just get a lot of hits from old documentation on Emacs when it used to have the old key binding...

Thanks,

Robbie

This should get you off the ground:

  (global-set-key "\e\e" 'eval-expression)

(For the future, you can find out answers to many such questions by
looking at various key bindings in the Emacs sources.)
