The Mysterious Windows Key
Have you ever noticed that key between Ctrl and Alt? Have you ever wondered what it does? Sure, clicking it will bring up the start menu, but it can unlock a host of other cool functions.
For example; if you are leaving for the day, but don't want to shut down your computer, hold down that Windows key and press the "L" key. You've now locked your computer. Or, if you are using Windows Vista or Windows 7, hold down the Windows key and tap the "Tab" key a few times. Pretty cool eh?
Many other key combinations do some amazing things using that mysterious Windows key. You can download a PDF listing many of these functions below. (Thanks to Michael Dunham for providing this list.)
