The Timeline is located at the bottom of the Captivate window. Each slide has a unique Timeline. You can use the Timeline to control the timing of any slide object. For instance, using the Timeline, you can force the captions to appear on the slide at the same time, or you can force one caption to appear as another goes away. The Timeline consists of the following features: Object Bars, a Header, a Playhead, and Playback Controls. The objects on a project slide are displayed as stacked bars on the left side of the Timeline. The Header at the top of the Timeline indicates time in seconds (and parts of seconds). The Playhead shows the point in time in which the slide is being viewed.
