What I am trying to do here is assign some pins to use the "Keyboard.h" library function ".write" while having other pins use the function ".press". The desired effect would be to have toggle switches operate on a basis of ".write" while having momentary switches use ".press". I have cannibalized this code from a popular keyboard macro repository, but I don't have enough knowledge to know if what I am trying to do is possible.

Sorry if this is in the wrong forum space.
