Adobe Acrobat allows you to view a PDF document in full screen. This mode is useful when reading a document online or giving a presentation using a PDF. In full-screen mode, only the document pages will be displayed, while items such as window controls, toolbars, title bar, status bar and menu bar will be hidden. You can also set various preferences for full screen mode, such as automatic page advance after a specified time, creating a slide show effect.
