I'll be honest up front and say that I have never actually tried it myself
first hand on an actual jukebox ...but as I understand it the keys are
grouped, electronically (so don't rely on the emulator here), like this:

Group 1: Down, Left, Right, Play
Group 2: F1, F2, F3, Up
Group 3: ON, OFF

You may detect only one key from each group in a single read.

NB. I am unsure exactly what does happen if you press (eg) F1 & F2
simultaneously.

OFF has a special feature which is that if you hold it for about 3 seconds
it will power down the unit - as I understand this is at a hardware level,
so is quite useless as a 'Shift' key.

Think that's all :)
