Click the Staff tool . Handles appear
on every group bracket in the document.
Drag the bottom handle up or down. Drag the
top handle left, right, up, or down. When you drag the top handle
horizontally, the entire bracket moves. When you drag either handle vertically,
you can make it appear to enclose even non-grouped staves.
Select a bracket handle and press BACKSPACE
to revert a bracket to its default length (so it encloses the staves of
a group).
