I am trying to associate the keyboard shortcut
Control + F10 with
gud-step in GUD in Emacs.
I thought the following would do the trick, but it doesn't:
(define-key gud-mode-map '[C-f10] 'gud-step)
My mistake. The above actually works. Sorry for the confusion. Instead of deleting the question, we can close this thread in case anybody ever needs to set up a similar keyboard shortcut.
