Re: Emacs keybinding of Ctrl-[

Hm, I couldn't find this in the manual.  Maybe that's because I am
using Xemacs, not Emacs?

Just like me.

Doesn't that say, that binding C-[ should work?  But this line:
 (define-key global-map [(control \[)] [udiaeresis])
does not have any effect. :-(
Maybe I just didn't understand it.

That's right!  In the meantime I managed to turn my capslock key into
a "super" key.  I could then map like this:
 (define-key global-map [(super \[)] [udiaeresis])

Unfortunately I can only use that key when in emacs.  I can't find how
to make use of it in the shell, an xterm etc.

Thanks anyway for your help!
