Hide or show a slide
If there is a slide that you need in your presentation, but you do not want it to appear in the slide show, you can hide the slide.
This is particularly useful when you have added slides to a presentation that provide different levels of detail on the subject matter, perhaps for different audiences. You can mark these slides as hidden so that they are not displayed in your main slide show, but you can still access them if you need to.
For example, a member of your audience might ask you to explain an item in more detail. In that case, you can reveal the hidden slides that contain those details. However, if time is short and the audience is comprehending the concepts that you are delivering, you may want to keep the slides with the supplementary information hidden so that you can continue your presentation without visibly skipping over slides.
In the pane that contains the Outline and Slides tabs, click the Slides tab.
Do one of the following:
To hide a slide, right-click the slide that you want to hide, and then click Hide Slide.
The hidden slide icon appears with the slide number inside, next to the slide that you have hidden.
To show a slide that you previously hid, right-click the slide that you want to show, and then click Hide Slide.
