There about a dozen pre-defined Windows Key combos. You may be able to change them by digging in the registry, but I wouldn't. But, Win XP allows you to set shortcut keys for any aplication. Just right-click on any .exe file, select Properties. Click the Shortcut tab in the Properties window. Then, press the keys you want to use. I believe you're limited to CTRL + ALT + a letter. Note: Some programs (rather rudely) set these kinds of shortcut keys when they are installed, possibly stealing a shortcut you established for something else.
