Interactive terminals, which are used by untrained operators to execute complex transactions, often result in confusion in the mind of the operator because of the very large number of alternatives available to the operator. This article sets forth a multi-purpose keyboard and display, having a regularized format to reduce operator confusion. The keyboard has four different functional areas. They are application, interaction, numeric, and control key areas. All four of these key areas are superimposed on an alphabetic keyboard to give a wide degree of versatility. The display also is pre-formatted into four areas. The four display format areas are current transaction step, customer identification data area, and a guidance area.
