Within PowerPoint, you can apply transitions to your slides and later tweak them aplenty. You can adjust the duration and timing of any transition, and even add a sound that will play while the slide transition happens. In addition, you can also play with some more options providing more control over the transition style applied to the slide — these are all placed in a single broad category called Effect Options. These Effect Options, as the very name indicates are related to the individual transition effects, and options may differ for each effect. Further, each transition effect may or may not provide Effect Options. These Effect Options enable you to have more control over the transition style applied to the slide.
