Yes, I use vim :) The spacebar is basically split into four buttons. The rightmost one is actually space. The leftmost one is shift. This means I only need one shift key as I don’t need to alternate left and right shift. The keys with arrows on them are not actually arrow keys, I use arrow keys on a layer. The left one pointing right is enter when pressed and FN when held. the right one is is -_ when pressed and a layer key when held. All the the mods on the left work like that too: tab when pressed, mouse layer when held. 0 when pressed, superkey when held. Esc when pressed, ctrl when held.
