Inputting ornaments with the popover
You can input ornaments and jazz ornaments using the ornaments popover, both during step input and by adding them to existing notes.
Procedure
Result
During step input, ornaments are input at the caret position. Trills last the duration of the rhythmic value of the note input at the caret position and have a default interval of a second, either major or minor depending on the context. If you specified an interval for your trill, the interval applies only to the first note in the selection, but you can also change the interval partway through trills.
When adding ornaments to existing notes, ornaments are input above the selected note. Trills are input above the first selected note, with an extender line across any subsequent selected notes.
