Check out more Karabiner Elements rules at Karabiner Elements rules library. However, if you prefer to go the manual route, you can use external config generators such as Goku or Karabiner’s own generator to create complex modification rules. With Goku, you get the ability to generate .json files, which you can edit and tweak to your requirements, whereas Karabiners’ web tool allows you to generate rules using its GUI.
