Like the others said you can map the keys however you want. I removed caps lock and put shift there. I mapped all the numbers to a numpad-like layout on it’s own layer, so all of those numbers and special characters are on one hand without needing to lift. The rest of them are on the normal number row on the main layer.

I actually don’t use the two “middle” buttons at all
