If you don’t want a slide to play during your presentation, you can skip it. Skipping is useful, for example, if you want to retain two versions of a slide but you want to show only one of them.
Skipped slides are editable and appear as a horizontal bar in the slide navigator. You can select them and interact with them just as you would other slides.
Tap the slide in the slide navigator, tap it again, then tap Skip.
To make a skipped slide play in your presentation, tap the slide, tap it again, then tap Don’t Skip.
