According to the manual, there are six commands for transposing notes:
These four are working:
Press Option ↑ to move notes up one staff position.
Press Option ↓ to move notes down one staff position.
Press Shift Option ↑ to transpose notes up a semitone.
Press Shift Option ↓ to transpose notes down a semitone.
But these two are NOT working:
Press Cmd Shift ↑ to transpose notes up an octave.
Press Cmd Shift ↓ to transpose notes down an octave.
When I attempt the latter, Dorico modifies my selection in unexpected ways, but does not transpose the notes. I’m in v126.96.36.1991.
Can anyone else confirm this?
