The topic of keyboard layers is closed for now

It’s important to understand: only part of what can be built on the Karabiner + Hammerspoon pairing is described here. I’ve shown the solutions I came up with for myself and really use every day: layers, signals, logic and scenarios.
The potential is much wider: you can assemble any combinations, add new modes, rules and context, and gradually bring control of the system to a state that suits you perfectly.
I’ll come back to this topic regularly and gradually expand and improve my setup, so the story of layers certainly doesn’t end here, it will only develop
