You already learned how to show the Advanced Timeline for Custom Animation within PowerPoint 2007. The main advantage of using the Advanced Timeline to edit your animation is that you can control the start time, duration, and end time of your animation to the most minute level. You are not limited to the time or speed presets that PowerPoint provides. For example, by using the Advanced Timeline you can animate a slide object very slowly to span over a whole minute or more by just dragging the start and end points of any animation bar outwards in the timeline.
