Gamgi->Exit asks confirmation to close GAMGI.
Because this is a very sensitive operation, users are not allowed to perform 
any other task until answering the question (not even consulting the 
Help).
Pressing 
Ok, GAMGI closes all windows and exits, 
without further notice and without saving any data.
Pressing 
Ctrl C over any GAMGI window or over the launching 
xterm window works exactly as selecting 
Gamgi->Exit.
Pressing the 
End key over any GAMGI window has the same effect.
When only one top window is open, selecting 
Window->Close 
has exactly the same effect as selecting 
Gamgi->Exit.
