Abstract
In an interactive display for a telephone terminal, movement between menu screens is controlled by hard buttons located on the telephone terminal. Directional arrow symbols, responsive to the switching action provided by pressing the hard buttons, are selectively employed in the display space of the menu screens for providing a visual indication to a user of available previous and/or next menu screens. These arrow symbols occupy minimal space in the display screens, yet enable the user of the telephone terminal to easily determine the availability of and direction to proceed to access additional available menu selections in the interactive display.
