According to wikipedia,
In computing, a keyboard shortcut or hotkey is a finite set of one or more keys that invoke asoftware or operating system operation when triggered by the user. 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”.
