Also worth remembering, you can use the export/import facility to create a second copy of a sequence (or entire scene) in your project, which can be subsequently modified. For example, you may want to create an animation with several scenes that will ultimately be edited together, each scene using the same basic environment and characters but with different events and sequences. You can create a basic "template" scene and export it, then import it as many times as required, setting the cameras, sequences etc. in each. Also handy for sequences, where a basic walk sequence can be copied, the copy being modified with, perhaps, the figure tripping over, and being based on the original walk sequence they will run together seamlessly when eventually sequenced together in Scene mode.
