Creating My Own Shortcuts

I'm glad to have read this, I still often navigate with my keyboard, but for some I've created my own [ctrl] [alt] shortcuts that I didn't realize were already present with the Windows key. In fact, the only thing I've ever used my Windows key for is hitting the Start button. I was un-aware that it could be used for anything else. I learned all my shortcuts before there WAS a Windows key, and I guess i just assumed little had changed...learn something new everyday...
