Emacs: by mistake binded M-x to a different function

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 ?

You could invoke M-: (or Alt-Shift-;) to run eval-expression. Then use global-set-key to reassign "M-x" to its default value (execute-extended-command).

If you're worried about having a lot of buffers open and losing your workspace, you can always enable the desktop extension, which will save and restore the state of your buffers and windows.

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)
