In compiz the "fit zoomed area to window" is pretty neat. It will zoom in so that a given windows covers the full screen.
What I'm missing here is a way to zoom out back to the default level.
I.e. if I'm zoomed in N%, how can I simply get back to 0% zoom?
I have a key to zoom out; but I need to press it a whole bunch of times which is not what I want.
I've also figured out that if I set "zoom level" to it's maximum (3.0), then my zoom out key does bring it back to 0%. But now the zoom in key goes too close and is unusable. I'm hoping there's a cleaner way to do this (one where I don't have to disable other functionality).
