 /* This keymap is designed for use with a German keyboard layout.
  * It is essentially the same as the default via keymap but adds combo functionality to type umlauts as well as lighting layers for various actions.
  * Toggling the combo feature also disables KC_LGUI so both can be turned off for gaming. If you want to get rid of it without reflashing new firmware, use KC_RGUI instead.
  * Layers 2 and 3 are currently unused but are configurable within via.
