/*
 * Keyboard: Atreus
 * Keymap:   replicaJunction
 * Version:  0.3
 *
 * This keymap is designed to complement my Ergodox keyboard layout, found in keyboards/ergodox_ez.
 * The Atreus keyboard is a 40% board whose design was heavily influenced by the Ergodox. I now
 * have both keyboards, so I've designed these layouts in an effort to make switching between the
 * two as easy as possible.
 *
 * Clearly, the Atreus is the limiting factor in this equation, so I've taken heavy advantage of
 * function and dual-role keys.
 *
 * The default key layout in this keymap is Colemak-ModDH. Information on that layout can be found
 * here: https://colemakmods.github.io/mod-dh/

// entirely and just use numbers.

// Note that whatever is set as layer 0 will be the default layer of the keyboard.
