But wait, there’s more! A third option I’m trying is remapping Caps Lock to Escape when pressed, and to Control when held down. You can set that up on macOS by using Karabiner-Elements and downloading a “complex modification”.
Also: yes, I’ve now removed both the Escape and Control keycaps from my keyboard to get used to this.
