First of all, thank you for his work that fantastic, I have not tried using it on my board, but will test soon as I can.

If you succeed it to work the buttons optimal, before I tried several options, and when he had to press more than one button at the same time, I always had some failed, for the value to be very near each other, but maybe I have only tried with the combinations that did not work, when I should have worn that worked.

Thank you
