the "windows" key

[Kjetil Halvorsen]

I got a problem. Using emacs, and having the "windows" key ("super" in emacs)
bount to an emacs function. But now, when keying "windows"-m, the
screen inverts colors!
Once more, it re-inverts. So it has become an idempotent function.

Seems like ubuntu have stolen my key binding! How to give it back to emacs?
