I'm trying to set the tab key to map a function. In my application, with tab I have to select next window in screen. I tried to define a simple function that displays a message; I used (global-set-key) to map this function on "M-h" (global-set-key (kbd "M-h") 'hello) It worked, message is displayed. Now, I tried same thing with tab-key (global-set-key "\t" 'hello) Apparently I don't receive any error. But, tab key doesn't display anything. I'm using emacs on windows, but tab key works correctly in other situations. Any suggestions?
Hmm, I'm not sure what's wrong, doing
(defun hello () (interactive) (message "hi!"))
(global-set-key "\t" 'hello)
seems to work fine for me. Does your hello function look similar? The only thing I can think to suggest is trying (kbd "TAB") rather than "\t" in the call to global-set-key. A lot of code I've seen in the wild and that I've written in my config does this. I'm not sure if there's any difference, but it's worth a shot!
