It does not work. What is strange is that if I put (defun souligne () (interactive)
(insert "_{}") (forward-char -1))
(global-set-key "z" 'souligne) when I press "z", emacs write "_{}" !!!
So in emacs, I try to M-x global-unset-key then _ but it does not work in emacs. the button _ still works !!!
I also wanted to press ^ and get ^{} and press $ and have $ $ but it not works !
Notice that for ( ) or {} it works fine
2) my second question is about an historical file and menu.Is it possible that emacs have a menu with the last 10 files that I opened ?
If you can help me, I would be very happy thx Etienne
