Alternative to the meta key

I use and love my Unicomp Classic 101. When I bought it I was primarily using Linux and didn't see the need to have a Windows (also known as meta, super, that-one-between-ctrl+alt, etc). Since moving to mostly Windows 7 though, I've noticed that there is functionality built around that key. I believe this is increasingly showing up in Linux window managers as well. If any of you are in the same boat as me, fear not! In Windows 7 ctrl-esc provides the same functionality!
