I’m not sure if this is the right place to point this out. It’s a minor but persistent frustration.
This is in Dorico SE 220.127.116.116 on an M1 Mac.
I can’t add B above current note. The Option-Shift works on all other note names, C-A, but does nothing when Option-Shift-B is pressed.
To reproduce, open a new score, Shift-N to go to note entry mode, type any note (say C), and then try Option-Shift-B, and no note is entered.
