You can mark any slide as hidden by clicking the Hide Slide button on the toolbar or double clicking its thumbnail. If a slide is hidden, it will be darkened, and a corresponding "hidden" label will be displayed on top of it.
Hidden slides are not displayed in the outline of the player. They are skipped during presentation playback. Please note that hidden slides still exist in your presentation and can be accessed using hyperlinks or action buttons on the other slides.
You can hide or unhide several slides at once. To do this, select them in the list by holding down the CTRL or SHIFT keys, and click the Hide Slide button on the toolbar.
