Windows users have been able to minimize every window on their desktop ever since keyboards with the Win key started showing up — just tap WIN + M on your keyboard, and every window is minimized. For Mac OS X, it’s not quite as simple.
Is this different than when I press the F11 key?
Yes, that only moves them to the side temporarily.
