/*
 Keymap is loosely based on DivergeJM's Nyquist keymap
 Major changes made:
  - DVORAK, COLEMAK, FUNCTION, MOUSE, and ADJUST layers have been removed
  - right 2u key performs backspace, not enter
  - LOWER layer controls function keys, media controls, and underglow
  - ARROW layer uses JKLI for arrow keys
  - Bootmagic enabled and bootmagic initialization key changed from space to enter
*/

// Layer names don't all need to be of the same length, obviously, and you can also skip them
// entirely and just use numbers.
