I just wanted to free a shortcut I had for “C-1” to let it behave the way it was meant with the command “digit-arguments”. This answer came in handy.

(global-unset-key (kbd “C-1”))
(define-key global-map (kbd “C-1”) ‘digit-argument)

By the way (a little tip) you can go: C-<digit ARG) instead of the C-u method; say to move 11 characters back, “C-11 C-b” is quicker than “C-u 11 C-b”, one less hit!


  1. didn’t you mean M- ?

    • @loquehumaine, not sure about your question but I did not mean “M-?” As far as I know that is not an already defined key-binding

  2. You know about the emacs manual, right? {global,local}-unset-key are documented in the emacs texinfo manual under “Customization > Key Bindings > Rebinding”. If you find that it is difficult to find a useful piece of information in the manual, consider reporting it as a bug to the emacs developers, so that the manual can be improved.

    • Anon, you are right, though maybe it’s me but it’s sometimes hard to find a piece of info in the documentation (nothing was returned with “M-x apropos rebind” RET, nor “C-h a rebind RET” ) What can you suggest to ease searches there?
      Oh, never mind, I see that “info-apropos” does actually find stuff. Thanks!

        Most of the time you will be looking in either the (elisp) or (emacs) manuals, so switch to whichever seems appropriate, and then you have direct access to its index by typing upper- or lower-case ‘i’ (I find the former more useful), or alternatively you can use C-s to isearch throughout the manual as well. info-apropos is important to have available, but usually not needed in my experience.

  3. If you use an alias as the permanent binding: (define-key global-map (kbd “C-1”) ‘my-Ctrl-1), you can then change the function your alias points to at any time with a single defalias call. A tiny saving.

  4. @Phil, thanks too for your tip!
