Choose Edit > Select Region.
The Select Region dialog box appears.
Enter the staff, measure, and beat with which
you want to begin and end the selection. For example, you can select
the Flute staff, measure 4 beat 2, through the Bass staff, measure 10
beat 1. See Select Region dialog box
for more information. The important thing to remember is that this feature
lets you select music without having to scroll to it (and wait for the
screen to redraw). You can even select music that’s not on the screen.
