Includes the standard layout for all keys except for the left-most column, which is remapped to these keys:
+-----------------+ | Mute | +-----------------+ | Volume Down | +-----------------+ | Volume Up | +-----------------+ | Function | +-----------------+
With Function held down:
+-----------------+ | Mute | +-----------------+ | Brightness Down | +-----------------+ | Brightness Up | +-----------------+ | Function | +-----------------+
And also with Function held down, "Print" (the lower right key) will trigger RESET (putting the controller into bootloader mode so it can be flashed).
