Many times, users just remove an animation and apply another one instead. The need to change an animation may arise for several reasons: You realize that another animation type would work better in a given slide, or you want to make all animations across the entire presentation consistent, or you want to use a more subtle or exciting animation. Whatever your need may be, you need to remove an animation and then add another one. PowerPoint’s Change Animation option makes this a one-click step.
