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