Add the possibility to address buttons with letters

[charlesbones]

Currently the function isPressed uses numbers as index, would it be possible to add also the possibility to address the buttons with letter a, b and c as in the silk screen?

[facchinm]

Absolutely feasible but would you prefer something like

buttons.isPressed('A')

or

buttons.isPressed("A")

or

buttons.isPressed(A)

?

They all come with different issues and drawbacks but are of course implementable

I would say option 2
