A trackpad, also known as a touchpad, is a touch-sensitive surface typically found on laptop computers and is used to control the on-screen cursor, allowing users to click, scroll, and switching between open applications.
Modern trackpads often support a range of multi-finger gestures, such as pinch-to-zoom, two-finger scrolling, three-finger swiping to switch apps, and four-finger swiping for viewing all open windows or desktops. These gestures are supported across various operating systems, including Windows, macOS, Linux, and Chromebook. Trackpads have become a staple in mobile computing for their compact design, allowing the user to navigate without having to connect an external mouse.
