I don't use any of these window managers myself, which is why I asked for 
examples.  I misunderstood his answer, and did not realize that users 
could use a window menu the way you describe it.

These are the kind of key bindings I had in mind, and a few Google 
searches showed a great variety of bindings accross window managers.

Anyway, it seems to me that this is tangent to the discussion.  The fact 
that some users use M-SPC x (in Emacs key notation) to maximize a frame 
(in Emacs parlance) does not seem to be a good reason to use the 'x' key 
to toggle the maximization of windows in Emacs.  At least I'll continue to 
use the 'm' key in my configuration for that purpose.
