Background

I’ve been messing with mechanical keyboards recently.¹ There was one in particular which is a 60% layout that I fell in love with.

The trouble with 60% keyboards though is that they can be pretty constraining for some basic operations (like navigation). Notice there aren’t dedicated keys for the up/left/down/arrows.
