ABSTRACT
This chapter covers shortcuts and tips for managing and replacing layers, creating markers and snapshots, and editing images in their original application. A large portion of using After Effects efficiently is to master some of the keyboard shortcuts. After Effects usually presents more than one way to do any given task. One of the most valuable tools in After Effects is markers: tags that can add to a comp or layer in the Timeline panel. Comp markers are used to help remember specific points in time in an overall composition. This makes it easier to coordinate multiple layers and keyframes to the same overall time. In addition to comments, marker start time, and marker duration, markers may also contain Chapter and Web Links, as well as Flash Video Cue Point and Parameters information. The Replace Source feature works on a layer-by-layer basis.
