If you don't like using the sections and/or the Hoist command as Derek illustrates, you can also keep a separate file of notes for each lecture, and make an overview/organizer by dragging the files into the notes. Then just click on the file icons when you want to go to that particular outline. If you need a completely different schema for different sections of the overall outline, this is one way you can do it without waiting for OO4 to arrive. It also allows you to organize a bunch of different documents without combining them.
