Do you have a secret slide with useful information that you would rather not delete? But what if you show this slide to your audience inadvertently? How do you cope with this problem? The solution is easy: you just hide the slide. Hidden slides don’t show up in Slide Show view, but they are still available to edit and to possibly unhide when you are ready to show that slide to the world.
