T-bones,
Crazy they are left out ? I would think something like the modifier first then the code. maybe?
Good stuff for the code bag though , sending and receiving those in both USB HID and BLE : - p
those tensy snips show what is indeed possible if only seeed pushed software support more.
it is what it is so the community picks up the slack when possible, support is amazing in supporting SO many products IMO.
