Q. Why can’t I “script” animation in PowerPoint 2010? All I can do is add animation?
A. The animation gallery (Animation tab, Animations group) has been expanded to make choosing one step animation much simpler. However, if you use more advanced animation techniques, you’ll need the Animation Task Pane. On the Animation tab, Animation group, click the Advanced Animation button. If you've used this pane in the past, it's virtually the same.
