"In computing, a keyboard shortcut is a set of one or several

keys that invoke a software or operating system operation

(in other words, cause an event) when triggered by the user.

The 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."
