Keyboard Maestro is essentially an IDE for automation. You create macros of actions that you can then easily call from Karabiner.
I share all the macros I have made here.
- Write once, never write again - Goes over how to use Typinator together with KM to automate writing text.
- How I manage my huge KM library
- KM forum - Great place to discuss all things related to KM.
- It is always better to run compiled Applescripts.
