Feature request: more keyboard shortcuts

Kanru, I know you love how flexible Reaper is!

Off the top of my head, I would love the following:

  • Transpose note a semitone up/down
  • Move cursor left/right by [grid value]
  • Change grid by .5/x2
  • Change grid to [Value]
    • I think more values would be cool. 1/2 note, whole note…
