In Adobe Acrobat, PDFs can be viewed in full screen mode. This comes in handy if you are reading an online document or making a presentation using a PDF document. In full screen mode, only the PDF pages are displayed on the screen, and the toolbars, controls, title bar, status bar, and menu bar are hidden. Also, the full-screen mode can be configured, for example, activate auto-scrolling (each sheet will be displayed on the screen for a specified time).
