ress to the PC,
   but if you hold down GPIO 7 and press GPIO 8, it sends a "B" press to

   You can extend this idea to multiple shift buttons.  If you define a second
   shift button, you can create chords, analogous to Alt+Ctrl+X keys on the PC.
   With a two-button chord defined, you can give a single button up to <i>four</i>
   separate meanings.  Pinscape Pico can handle up to 32 shift buttons, although
   I tend to think two will be enough for most pin cabs.
