AltGR => ISO_Level3_Shift key

AltGR => ISO_Level3_Shift key

[Chmouel Boudjnah]

Hi,

We have a problem with the ISO_Level3_Shift key which is bind to AltGR
on international keyboard under latest XFree[1], the key return key-3
under Emacs. 

The Key doen't do as same as ModSwitch like with the older XFree.

For example when i need to find the @ char on a french keyboard, i do
a C-s AltGr and before i want to type 0[2] Emacs exit from the search
because he doen't think that key-3 is a compose key.

Is there a way to make it ISO_Level3_Shift => ModeSwitch (please other
solution than via xmodmap i speak about distribution wide).

Cheers, Chmouel.
