R167 massdrop ctrl
The main layer is a ~standard QWERTY layout with the ALT/GUI swap for macOS
in addition to shifting the Fn key one to the right so cmd/alt line up nicely.
Addionally, I rarely use PgUp/Dn, so I've remapped those to volume control.
The most interesting bit is the shortcut Fn + Esc which triggers the macOS sleep
shortcut (CMD + ALT + Eject) and then disables LEDs since the computer will wake up
peripherals even while the display is asleep. Keyboard is returned to all LEDs on after
pressing any key.
