Open the Windows Explorer with zero clicking

Using the computer sometimes means a lot of time finding and opening files and folders. And that usually entails tons of mouse clicking.

Do you know you can bring up Windows Explorer using a simple 2-key shortcut? If you haven't discovered it, try pressing Windows Key and E together.

The Windows key is commonly found in newer keyboards. This shortcut works for XP and Me, but I'm not sure about Vista since I haven't used it.
