Does anyone here know anyone (anyone - especially someone who's a 'gamer') who actually uses and appreciates the Windows keys on their keyboard?
Yup.
Me.
Smack them for me if you do, please.
I decline to smack myself, thanks.
Why? Well, I can count the number of times I've hit the Windows key in a game by accident on one hand. With several fingers to spare.
There's several useful shortcuts in XP that use the Windows key:
Win-E - explorer
Win-Break (aka Pause) - System Properties
Win-L - lock screen (or go to quick switch screen, depending on how things are setup)
Win-D or Win-M - minimize everything (Win-Shift-M undos)
Win-R - Brings up the Run... dialog
A few apps that can use it as well. VirtuaWin, a virtual desktop manager lets you use it for switching between desktops. You can configure it for other keystrokes, but these are by far the easiest.
The Quickswitch PowerToy, Win-Q lets you switch between users quickly (if you have fast user switching enabled).
Now the other key that MS added -- the "context" key that's only on the right side of the space bar.... that one I find useless. I've tried using it before to help semi-repetitive tasks, but even then it wasn't of much use.
The Win key could be a lot better if MS would let you bind program shortcuts to it, but for some silly reason you can't. If you try it gets changed to Ctrl-Alt-key.
