PocketMatrix

I have converted the 0.4.5 button demo code so that I can identify the button down & button up events & this is working ( using the same onscreen rectangles as the original demo + some text).

What I can't figure out is how to reference the key definitions so I can tell which key is pressed. I spent aged ( maybe 2 hours ) looking at the input.c input.h & pocketpc code but still could not figure how to get the values.

So I know a button has been pressed/released but not which one ( vkLeft etc )
I know this must be easy when you know how but I'm totally stuck
