Hm.

That is all supposed to work (except we don't see key combinations
intercepted by the window manager before they reach us).  Problems due
to configuration problems of your keyboard are supposed to be solved
as explained in

http://www.gnustep.org/resources/documentation/gnustep-gui_6.html#SEC43

or graphically by running

[if it still works].


Assuming that, you have omitted most essential information:

A. what happens when you run GSTest.app/KeyboardInput ?

B. did you configure your gnustep keyboard ?  If so, how ?

I need more information to attempt to diagnose, but with the few info
I have, my guess is that there is something non-standard in your
keyboard or in your X keyboard mappings, and you haven't configured
your gnustep keyboard to account for this strangeness.  For example,
if AltGr is not Alt_R on your keyboard, then the default gnustep
configuration would treat it as a normal key, producing a key down
event when you press it, and no alternate mask unless you press AltGr
together with Alt_R (whatever that key is on your keyboard).
