Transitions in PowerPoint use special effects to go from slide to slide. Learn all about using PowerPoint transitions in this free lesson.
Normally, in Slide Show view you would advance to the next slide by clicking your mouse or by pressing the spacebar or arrow keys on your keyboard. The Advance Slides settings in the Timing group allows the presentation to advance on its own and display each slide for a specific amount of time. This feature is especially useful for unattended presentations, such as those at a trade show booth.
If you need to advance to the next slide before an automatic transition, you can always click the mouse or press the spacebar to advance the slides as normal.
