Drag any staff up or down to move the staff
vertically. You can drag more than one staff at a time if you choose
several at once (by SHIFT-clicking or by drag-enclosing their handles,
so that they’re highlighted). If you have many staves, you can move all
except one or two as follows: Choose Edit >
Select All to highlight the handles on all staves. Then
SHIFT+click the staves you don’t want to move; when any staff is selected,
a SHIFT+click “deselects” it. Then, as before, drag any selected staff
to move all selected staves at once.
