In keyboard music, when we want to indicate that a note written in a stave should be played by the other hand, we should use a partial square bracket. This bracket includes the note to be shifted, and is open in the direction of the other hand’s stave.
In Dorico we can have brackets for non-arpeggiato notes. However, we can’t let them open on one side. Is it something I’m missing, or a feature I should ask?
