Highly recommend you look into keyboards that have "Enter" and "Backspace" reachable by thumb/index fingers. I've been dailying a TECK for nearly a decade, and it's helped immensely with RSI.
Their new Clevo keyboard is a bit different, so can't vouch for it, but my SO likes it so far as first foray into ergo keyboards: https://trulyergonomic.com/
