Another major edit you may make to an existing presentation is to change the transition effects on a slide.

Transition effects are animation options within a presentation. You cannot see the transitions in action from the static presentation view of slides. But when you start the actual slideshow, transitions will dictate how the presentation progresses from one slide to the next. Transitions can be used to set specific time intervals before moving forward in the show, or can be used to make slides change with the click of a mouse button. Transitions also change the way a new slide enters or exits the screen.

To edit transition effects, you need to access the Transitions tab. From this area you can edit, delete, or add transitions to a slide.

If you hover your mouse over a transition option, you will see a brief description of that transition. Some effects have several options. For example the Wipe transition could start from the right, top, left, bottom, or other directions. The Effect Options dropdown menu is to the right of the transition options.
