Comment 20 for bug 161960

The Menu-keys is used for context-menus in Windows. Like right-click.

The Win-key can still be used for Compiz and other stuff, example if you use Win-key + another key.
But if you only press Win-key, and no other button, it can bring up the menu, on KeyUp event.

if(key=winkey & no_other_key_pressed) { show_menu(); }
elseif(key=winkey & some_other_key_pressed) { do_whatever_that_does(); }
