In Microsoft PowerPoint 2010, you can set an animation to trigger when you click on an object. This is a simple way to add and control interactivity to your presentation. To add an animation trigger, select an object that already has animation applied to it.
On the â€œAnimationsâ€ tab, in the â€œAdvanced Animationsâ€ group, click â€œAnimation Paneâ€ and then select the animation that you want to trigger. Back in the Advanced Animation group, click and hold on â€œTriggerâ€ and select â€œOn Click ofâ€ and select the object for which you wish to trigger the animation when clicked.
