I am trying to test my Keyrah v2 with a real c64 keyboard on Amiga Forever under Windows. I noticed that the keys are not mapped correctly, so I went looking for a test program, and found your program that is very nice.

I would like a feature to test the modifier keys as well, because I noticed that even though the keys appeared to be mapped correctly when typing the regular keys without modifiers, but when holding shift and C= keys the results were not correct so I needed to go through the emulator and remap the keys correctly.

Your program would be very useful if it had an option to show the modified keyboard so I could see if the resulting keypresses are resulting correctly.
