-# Brickbots keymap for plaid
-Original copyright 2019 Takuya Urakawa (dm9records.com)
-LED Support added by Richard Sutherland (rich@brickbots.com)
-
-This layout is based on the Planck layout, with esc/tab swapped and an extra
-ctrl key in the bottom left corner. It includes an adjust layer (6)
-accessible by holding the lower and raise modifiers (MO3 and MO4) together.
-The adjustment layer is used to set the behavior of the two LEDs:
-
-**Modifier Mode:**   
-Activates when any modifier (shift, alt, os, MO) key is held
-down.  LED turns off when key is release
-
-**Blinkinlights Mode:**  
-Random chance of state change on each keystroke.
-
-**Keypress Mode:**  
-On for any keypress as long as the key is pressed
-
-**Carriage Mode:**  
-Turns on when enter is pressed, turns off when any next key is pressed
-
-To set the behavior of an LED, and save it to eeprom, hold the
-raise/lower keys together to access the adjust layer, then use
-the keys indicated below to set the behaviors
-
-* q = Toggle Red LED state, deactivates any other modes
-* w = Toggle Green LED state, deactivates any other modes
-* e = Set RED LED to modifier mode
-* r = Set GREEN LED to modifier mode
-* t = Set RED LED to Blinkinlights mode
-* y = set GREEN LED to Blinkinlights mode
-* u = set RED LED to Keypress mode
-* i = set GREEN LED to Keypress mode
-* o = set RED LED to Carriage mode
-* p = set GREEN LED to Carriage mode
