Full-Screen Mode is a feature available in many software applications and web browsers that allows users to expand the display to cover the entire screen. This mode eliminates distractions by hiding toolbars, menus, and other interface elements, providing a more immersive experience. It is commonly used in applications like video players, presentation software, and web browsers. Activating Full-Screen Mode is usually simple, often achieved by clicking a button or pressing a specific key, such as F11 on a keyboard. Users can exit this mode by using the same method or pressing the Esc key. This feature is particularly useful for activities like watching movies, playing games, or giving presentations.
