the key on the typewriter keyboard that shifts from lower-case letters to upper-case letters; shift
Microsoft Computer Dictionary
n. A keyboard key that, when pressed in combination with another key, gives that key an alternative meaning; for example, producing an uppercase character when a letter key is pressed. The Shift key is also used in various key combinations to create nonstandard characters or to perform special operations. The term is adapted from usage in relation to manual typewriters, in which the key physically shifted the carriage to print an alternative character. See also Caps Lock key.
