Question

By mistake I have binded M-x ( used for doing all the operations ) to a newly defined function ? How do I unbind it ? Now Alt-x always executes my function 🙁 I dont want to exit emacs and restart again, I have lot of buffers open, so is there a way out here ?

Answer 1

The command usually run is execute-extended-command, just rebind it.

To rebind it, you have several options:

1. Just make what you did before, but just use instead your own function above mentioned execute-extended-command. If you did it with M-x command, then you maybe dont know, but M-x is not only produced by Alt-x, but as there are keyboard layouts that have no Alt (or Meta) key, you can use Esc x instead.

2. Rebind it with elisp command. To do this, change to the *scratch* buffer, enter
   (global-set-key (kbd "M-x") 'execute-extended-command) and execute it with C-j.

3. Maybe by using the menue (I usually dont use it, so I am not sure on this point)
