Remap Keyboard

Hi,

Is there a way to remap key assignment to play note for piano roll? (For normal PC keyboard)
Example;
For now when I press q key in piano roll, playing C4 note.
I want to change that example when I press q key, playing G7 note.

If there is now way for that, can I write?
For that; Which header and cpp files are required, those I must know or investigate?

The issue does not name any files, tests, or entry points. Start by locating the piano roll's keyboard input handling and determine how note assignments are represented; the work is done when users can remap PC keyboard keys to chosen piano-roll notes and the behavior is verified.
