PowerPoint’s animation options allow users to create a plethora of movement effects, all the way from the amazing to the dizzying. However, most of these animation effects have events associated with them — the three main events are On Click, With Previous, and After Previous. When you use the On Click animation event, PowerPoint offers an extra option so that your animated objects swings into movement when you click an entirely different object on your slide — this extra option is called a Trigger animation — you cause a click on one object to trigger an animation of another slide object. Also, you can you Trigger animations to cause media events as well, such as playing a sound or video clip. As mentioned earlier, we would like to paraphrase that Trigger animations work only with an On Click animation event applied to the animated object.
