Copying a staff to a new staff

For the record, the best way of doing this is:

1. go to the staff whose notes you want to copy.
2. Press Ctrl+Home to select the first note on the staff.
3. Press Ctrl+Shift+End to select to the end of that staff.
4. Everything on that staff should now be selected so press Ctrl+C to copy
to the clipboard.
5. Go to the other score.
6. Go to the staff you want to paste the notes into and press Ctrl+Home to
go to the start of that staff.
7. Press Ctrl+V to paste everything onto that staff.

You need to be careful about what you select in the first score and where
you paste it in the second score. The steps above are good for copying
things across one staff at a time.

After you've made the selection in the first score, you can do Plug-ins >
Access > Include / Exclude. This opens a dialog which shows you which staves
are included in the selection. Use this to double check before copying. (You
can also play the score; only the selected staves will playback when a
passage is selected.)
