In the RB Notation window, you can press the numpad "Ins/0" and "Ins/." keys to highlight and audition notes through the currently assigned synth. You can also use the Ctrl-Left and Ctrl-Right keys to perform the same functions.

When a chord is encountered, RB highlights and plays the chord notes as a "unit".

All of it GREAT functionality, because you can then "Up" or "Down" any highlighted note or chord to easily change note values.

However, it would also be useful if INDIVIDUAL notes in a chord could be highlighted/auditioned with the computer keyboard navigation, so that then INDIVIDUAL notes in the chord could then be edited Up or Down.

Being able to select an entire chord is great as is, and being able to have a way to alternately select individual notes in a chord would be gravy.
