Caps lock is probably one of my least used keys and I finally found a use for it.

My external keyboard has a hyper key (Alt+Shift+Ctrl+Cmd) that I use for global shortcuts like launching or switching between my regularly used apps (like a faster command tab) and running some automations.

Got the same thing going on the Macbook Pro by remapping caps lock to hyper (and a more reachable esc on short tap).
