Autohotkey script to toggle minimize/restore?

I am looking for a script to toggle between minimize and restore for Windows 7.

Answer

Toggling between Minimize and Restore doesn't make much sense as you'll need the Window in focus (or some other way) to send it the command.

Assuming you really mean toggle between Maximize and Restore...

I have these in my AutoHotkey.ahk. You'll be interested in the "F3" mapping which really is Ctrl-Shift-3 in my setup.
