/*
 * Keyboard: Ergodox
 * Keymap:   replicaJunction
 * Version:  1.2
 *
 * This keymap is designed to complement my Atreus keyboard layout, found in keyboards/atreus.
 * The Atreus keyboard is a 40% board whose design was heavily influenced by the Ergodox, and I now
 * have both keyboards, so I've designed these layouts in an effort to make switching between the
 * two as easy as possible.
 *
 * I've also tried to make use of the extra keys on the Ergodox in as logical of a manner as possible,
 * adding to the layers in the Atreus config without disturbing what's there already. This allows for
 * things like F11-F20, the Application (Menu) key, and better media key placement.
 *
 * The default key layout in this keymap is Colemak-ModDH. Information on that layout can be found
 * here: https://colemakmods.github.io/mod-dh/

     * Provides a mouse overlay for the right hand, and also moves some "gamer friendly" keys to the left, such as space.
     * This layer also removes a lot of dual-role keys, as when gaming, it's nicer not to need to keep track of those.
