After doing some research I found out detecting the command key will be difficult at best. The key word can't do it. The reason why the control, and shift key can be detected using the key word is because the control and shift key add to the value of the letter key being pushed. It is just a matter of knowing the range that each letter key will be in when pushed with a modifier key. The command key does not alter the value of a letter key when pushed, so detected it being pushed with the key word isn't an option. 

The only work around that actually works with QEMU right now is to detect the control key as the command key. I know you don't like this idea very much, but it does actually work and doesn't break any thing. Also, no patch is permanent. If someone does figure out a way to integrate the command key into QEMU, I can always change the get-key-map word to use the command key. 

We should stick with the get-key-map patch for now.
