Moving the start/end positions of ossia staves
You can move the rhythmic start and end positions of ossia staves after you have added them. Because you can move the start/end of ossia staves independently, you can also lengthen/shorten ossia staves.
Procedure
Result
The rhythmic start/end positions of the selected ossia staves are changed.
Only one ossia signpost can exist at each rhythmic position. If an ossia signpost passes over another ossia signpost as part of its move, the existing ossia signpost is deleted and replaced by the one being moved. For example, if you move the start signpost of an ossia over its end signpost, the ossia now continues up to the next ossia on the staff or the end of the flow, whichever comes first.
You can undo this action, but any ossia signposts deleted in the process are only restored if you moved the ossia signpost using the keyboard.
