Peeking at the Desktop
The final section of the Windows 7 taskbar is the Peek button. This access another new feature of Windows 7 dubbed Aero Peek. Hover your cursor over this button (actually a thin translucent slice at the very end of the taskbar), and all the open windows on your desktop go transparent so that you can see the contents of the desktop below.
Click the Peek button, and all your open windows minimize. It's a nifty way to quickly view or access the gadgets and icons on your desktop.
