If you let the cursor hover over a particular animation, you’ll be able to see a preview of that transition in the background. This is a great tool that lets you test a variety of animations without having to constantly use the Undo option.
Step 3: Once you’ve found the transition you want to apply, click on it to return to your slide. You can now modify the animated effect by choosing Fast, Medium, or Slow from the Transition Speed drop-down list. At any time, you can pause for a moment and see how your transition will appear by clicking the Preview button.
