AltGr-q in terminel

Hello,

I'd like to use a german keyboard, but I can't figure out how to prevent fluxbox from disabling any character created with AltGr.
On the console, AltGr-q inserts a "@", running fluxbox a "q" is shown. 
Is it possible to add an entry to the keys-file to add AltGr-q as a shortcut so the @ is inserted ? Or is there some other possibility?
Thanks.
