DM42 possible for audio beep keypress feedback?

[lemontea]

Hi, is there a way to set the DM42 so that it makes a beep sound for keypresses?

This helps confirm keys are actually pressed.

The keyboard is still not that easy to use. I don't quite know why, but the HP calculators don't give me this kind of problem. I seem to have to err on the side of pressing hard on the DM42 keys to ensure digits or operations are not missed (despite having flexed the keyboard and flash upgraded).
