For years I’ve been using caps lock as a control/cmd key.
Lately, when I was researching keyboard layouts, I stumbled upon Extend concept for Colemak [1]. I decided to try it out and, for me, it is a game changer.
It is somewhat problematic to work through muscle memory, but I really think it’s worth it, especially since I skip between various editors a lot and adjusting each is a pain and this seems to solve it nicely. I know that for Extend there are multiple implementations for Windows, Linux and Mac.
