Oh yeah I couldn't make it work with letters. Rather I added tap behavior to modifiers. In QMK my command keys are Esc and Enter when tapped, shifts are parentheses (like the space cadet keyboard), controls (outside of A and ;) are single and double quote, Options are braces, and hypers are angle brackets (which I should probably change to brackets since I don't really write JSX/TSX/HTML much any more)
