    I have a bunch of key assignments that I make.
    To show them on the "keyboard" you can use a graphics program like Paint to add them to the relevant .bmp file in the program directory. There are three, small.bmp, medium.bmp and large.bmp . Remember to change the Properties on the Folder holding the program. Win7 has it as Read Only.
