Hi,
Keep moved Notes within Key was implemented in C10.5. This seems to work when notes are moved by mouse. It would be great to have the option to “Nudge notes within key” as well. So when we do nudge with KC, it fall into pitch belong to the key.

If this option is activated, and you move notes vertically (to transpose them), you will be restricted to pitches within the current key.
