One word of warning. Changing the hide or show empty staves option will *dramatically* alter the layout of the score. It also only applies to selected bars. So, if you use this approach, make sure that you do a final pass for hiding and showing staves throughout the entire score before you print. It's better to use focus on staves for this. It canb e useful if you're working with two staves that are a long way apart. A simple example, you're looking at a piece for eight voice choir and want to look at the second bass and first soprano together. Sibelius remembers which staves were being shown when you turn focus on staves off. To show those staves again, press Escape before turning focus on staves back on.
