Re: characters problems in terminal

[Riccardo Mottola]

Hi,

I checked "System preferences" and I have no setting (= everything is 
set to "None") this means I am using GNustep's default.

Actually, do you think this is correct? I checked that, for example, on 
Windows "Alt-F" opens the file menu, but AltGr-F does not.
This is true under GTK applications like Thunderbird too.

Well, to be honest i never used those features. I think it is wrong to 
"force" AltGr here But I wonder if AltGr can be distinguished from 
Right-Alt? I expect them to be different keys.

Ideally, I would use windows key as command and Left-Alt as alternet 
(emulating Mac/Next behaviour) and give a use to that offending-labeled 
key on my keyboard. :)
