Yes, it seems to be generally true.

I don't know offhand how switching windows in response to cmd-` is implemented in Cocoa (or ctrl-tab Gnome, 
for that matter), but I suspect that it's handled by the NSApplcation object and that it requires that the 
Windows menu be managed by that object. There's nothing in GtkosxApplication to do that. I think that's more 
likely to be the problem rather than that cmd-` is getting eaten by Gtk-2.

As long as your application uses GtkActions you can configure shortcuts with an accel map. This is 
demonstrated at line 877 of test-integration.c.
