For anyone confused by the title of this stupid post, refer to Frank Zappa's discography for a clue.
Aero Shake is a neat little nifty coolio feature that may seem meaningless, but is actually quite helpful. You simply click and "hold" on the title bar of any open window, and then shake the mouse side to side quickly. It drops all other windows to the task bar and keeps that window open. Sort of like shaking it loose from the other windows around it. If you have Windows 7 installed with Aero support enabled, give it a try. It's pretty cool.
