Distances
        You can set almost every aspect of your 
 music’s appearance; here are a few distances and measurements you can 
 change easily.

            - Click 
 the Staff tool   . .
- 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 all of the staves’ handles. 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.
