Emacs global-set-key to C-TAB

Question

I\'m trying to set a key-binding to Ctrl+TAB in Emacs. I used the following call:

(global-set-key (read-kbd-macro \"C-TAB\") \'my-func)

Howeve

Answer 1

Unlike others have suggested, it is a good idea to use kbd (or read-kbd-macro which is basically the same thing) in case you ever want to use the same configuration files in other versions of Emacs; kbd works across several versions of Emacs and XEmacs, where the internal representation of key sequences are different.

(global-set-key (kbd "") 'my-func)

The input format used by read-kbd-macro is documented in the docstring of edmacro-mode:

• The special words RET, SPC, TAB, DEL, LFD, ESC, and NUL represent special control characters. The words must be written in uppercase.

• A word in angle brackets, e.g., , , or , represents a function key. (Note that in the standard configuration, the function key and the control key RET are synonymous.) You can use angle brackets on the words RET, SPC, etc., but they are not required there.

This is written somewhat unfortunately; the TAB referred to in the first bullet point is the ASCII character for TAB, and adding the Control modifier does something nonsensical to it. When you press Control-Tab, Emacs sees it (via your windowing system; it will not work in a text terminal) as with a Control modifier, which you can represent as C- or .
