Anyone else never heard of this?
I was doing a little digging, when I read that there were some new features in 7.
One of them is Aero Shake, a 'shortcut' of sorts, allowing you to take a window, and make it the only one open.
To do this, when there are multiple windows open, grab a window by the title bar, and shake it left and right. This will minimize all other windows to the taskbar.
Pretty cool, if I do say so myself.
