Abstract
Abstract A keyboard entry device with video display for multiple language use. A language selector establishes the language mode of the machine, and the entire keyboard font is displayed on the video screen in the relationship of the keys on the keyboard. Display is either at operator request or machine controlled intervals and may be displayed on only part of the screen or the text being composed may be temporarily removed from the screen and the entire screen used to display the characters in a key related position. Thus, the operator has the capability of locating keys while learning the new keyboard relationship, or refreshing memory for reassurance.
