[Q] mk16i HW keyboard config files

I sit at the computer for two days, just searching the solution, but nothig.

In the stock, .587 kernel based ROM, which files are the hardware-keyboard config files?

And second question.

Can i copy these files from the stock ROM, and paste it to another "cooked" one? My goal would be to fix the "sym" button, and the arrow keys.

Thanks.
