RE: Suggestions on HP21 restoration
Very nice projects Andrew - the RP2040 is cheap, small, powerful, and available!

For the original question
- perhaps use a combination like shift-DSP to bring up a menu, using the 4 function keys on the top row
- perhaps use long-press as a way to get another function on a key
