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 http://stackoverflow.com/questions/7549259/is-there-a-quick-way-to-unbind-keys-in-emacs 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!
