For such a huge push as the one Microsoft gave to get the Windows Logo Key included in all keyboards destined to work with Windows, it sure seems like they’ve neglected to do anything with it. Of course, it also seems like Clark Kent is a mild-mannered reporter for the Daily Planet, but boy do I have a shocker for you. 

In fact, there is a sizeable amount of shortcuts activated by the WinKey, but no definitive list from Microsoft (or anyone else that I’m aware of.) All of the WinKey shortcuts are system-wide, so you can focus the taskbar no matter what app you’re in. Many of these shortcuts were added for Windows Vista, and while some are obviously new (see: anything controlling the sidebar), some might not be so easily spotted. If I have missed any, go ahead and wave that fact around like a Special Olympics gold medal (I’m gonna get sued for that one.)

• - Opens the Start Menu. 
• + E - Opens an Explorer window. 
• + R - Opens the Run dialog. 
• + T - Focuses the taskbar. 
• + U - Opens the Ease of Access control panel. (Vista)
• + D - Shows the desktop, hiding all windows. Not the same as minimizing. 
• + F - Opens the Search window. 
• + G - Focuses the sidebar gadgets. (Vista)
• + H - Unknown effect. 
• + L - Locks the screen. 
• + C - Unknown effect. 
• + V - Unknown effect. 
• + B - Focuses the system tray. 
• + M - Minimizes all open windows. 
• + Tab - Flip 3D (Vista)
• + Space - Focuses the add gadget button on the sidebar. (Vista)
• + 1, + 2, etc - Opens the corresponding button on the quicklaunch bar.

And there you have it. For the ones that say “Unknown effect,” I included those because if a key combo doesn’t exist, + Z for example, pressing it just ignores the and inserts a z. With those, nothing visible happened. Who knows, maybe I separately called in orbital strikes on Richard Stallman, Linus Torvalds, and Steve Jobs with those shortcuts.
