Duplicating Layers

As you learned in Chapter 4, you can add a footage item to one or more compositions as many times as you like, creating a new layer each time. However, it's often easier to duplicate a layer that's already in a composition, particularly when you want to use its edit points or other properties (such as masks, transformations, effects, and layer modes). When you create a duplicate, it appears just above the original layer in the stacking order. The duplicate uses the same name as the original, unless you specified a custom name for the original layer. When the original layer uses a custom name, duplicates have a number appended to the name; subsequent duplicates are numbered incrementally.
