In a PowerPoint 2007 presentation, you can hide a slide just in case you'll need it later. Create hidden slides if you anticipate having to turn your presentation in a different direction — to answer a question from the audience, prove your point more thoroughly, or revisit a topic in more depth. Just right-click and choose a couple of commands to display a hidden slide.
Although you, the presenter, can see hidden slides in Normal view and Slide Sorter view (where their slide numbers are crossed through) the audience doesn't see them in the course of a presentation.
The best place to put hidden slides is at the end of a presentation, where you know you can find them. Follow these steps to hide slides:
1. Select the slide or slides.
2. On the Slide Show tab, click the Hide Slide button.
You can also right-click and choose Hide Slide.
Hidden slides' numbers are boxed in the Slides pane and Slide Sorter window.
To "unhide" a slide, select the slide and click the Hide Slide button again or right-click it in the Slides pane or Slide Sorter window and choose Hide Slide on the shortcut menu.
Hidden slides don't appear during the course of a presentation, but suppose that the need arises to show one. Before showing a hidden slide, take careful note of which slide you're viewing at the moment. You'll have to return to this slide after viewing the hidden slide.
Follow these steps to view a hidden slide during a presentation:
1. Right-click the screen and choose Go to Slide.
You see a submenu with the titles of slides in your presentation. You can tell which slides are hidden because their numbers are enclosed in parentheses.
2. Select a hidden slide so that the audience can view it.
How do you resume your presentation after viewing the hidden slide? If you look at only one hidden slide, you can right-click and choose Last Viewed on the shortcut menu to return to the slide you saw before the hidden slide. If you've viewed several hidden slides, right-click the screen, choose Go to Slide, and select a slide to pick up where you left off.
