Keys are just integers in Emacs. There is nothing that makes any integer special wrt to keys. > Also, correct me if I'm wrong, but my understanding is that the form [?= \C- ] > is generally preferred over the form "\C- ", for a key binding. These two key sequences represent quite different bindings. You can't ge= t one override the other, it depends on the terminal which key you receive on typing C-space. > If so, that makes matters worse in cases like this. > > This form is good: > > (defcustom my-key [(control ?\ )] "My key sequence.")
