Remapping IBM right alt key to the windows key so that you have one click desktop access

One of the few benefits of a windows key on a computer is that you can have a shortcut to minimize all your windows at once to get to your desktop. However, IBM & Lenovo thinkpads don't have a windows key. After some searching, I figured out how to remap a
keyboard key to something else. I realized that I never used the right Alt key, so remapped this to the windows function, and Voila! I have the ability to minimize windows with a single keystroke (Right Alt+M).

This website explains how to do it.
