In computing, a keyboard shortcut is a series of one or several keys that invoke a software program to perform a preprogrammed action. This action may be part of the standard functionality of the operating system or application program, or it may have been written by the user in a scripting language.
The meaning of term "keyboard shortcut" can vary depending on software manufacturer. For instance, Microsoft differentiates keyboard shortcuts from hotkeys ("mnemonics" on Windows) 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—whereas a "hotkey" on Windows is a system wide shortcut that is always available in all contexts as long as the program responsible for it is running and not suspended.[ambiguous]
