Ever received a slide deck from someone, and some of the slides look greyed out? And, when you run the slide show (using F5) these greyed slides don’t appear! How can this be changed so that the slide is visible? These instructions are for Libre Office or Open Office.
1. Open the slide deck.
2. Highlight the greyed out side.
3. Select “Show Slide” from the popup menu.
If you follow the above procedure on a regular slide that is not hidden, you will notice that the “Hide Slide” menu item appears where the “Show Slide” menu item should have been. So, the feature allows you to toggle any slide from visible to hidden and back-again.
