Keyboard functionality refers to the various tasks a keyboard can perform when connected to a computer or device. It allows users to input text, execute commands, and navigate through software applications. Each key on the keyboard corresponds to a specific character or function, enabling efficient communication and control. In addition to standard keys, keyboards often include special keys like Function keys, Arrow keys, and Modifier keys (such as Shift and Ctrl). These keys enhance productivity by providing shortcuts and additional commands, making it easier for users to interact with their devices and complete tasks quickly.
