I have two control keys! They’re under D and K, through the miracle of mod-tap. Look into home row mods, it’s a game changer. Here’s my keymap for reference — it’s a bit of a work in progress, I keep finding little things to tweak or improve.
As it stands, the two outer thumbs (App/Alt) aren’t even mapped at the moment, they’re too tucky for my hands, and the outer row on the left isn’t exactly what the cap legends say, either.
