Using My Full Keyboard as an App Launcher with Goku Simultaneous Layers (Simlayer)
Goku has a concept called a simlayer. A simlayer allows you to press any single key on the keyboard, then any second key while holding the first and trigger an arbitrary action as a result. I'm going to write a karabiner.edn config that opens Firefox when you press <kbd>.</kbd>+<kbd>f</kbd>.
