In computing, a keyboard shortcut is a finite set of one or more keys that invoke a software or operating system operation when triggered by the user. A meaning of term "keyboard shortcut" can vary depending on software manufacturer. For instance, Microsoft differentiates keyboard shortcuts from hotkeys (mnemonics) whereby the former consists of a specific key combination used to trigger an action, and the latter represents a designated letter in a menu command or toolbar button that when pressed together with the Alt key, activates such command. Keyboard shortcuts are typically an alternate means for invoking one or more commands that would otherwise be accessible only through a menu, a pointing device, different levels of a user interface, or via a command console. Keyboard shortcuts generally expedite common operations by reducing input sequences to a few keystrokes, hence the term "shortcut".
