Alternate buttons

My Digitakts buttons arent working (AMP, Right arrow Key, 15, 7) and I am waiting to hear back from Elektron.

In the mean time for sound pool editing and menu diving is there a way I can access the same functions in an alternative way? The right arrow key seems to be very important for this sort of thing.

These buttons have been tested with a multimeter and come back okay but not detected by Digitakt.
