Abstract

A calculating device and related method for accessing and selecting among multiple key functions with a minimum of keystrokes. The keyboard includes menu keys corresponding to menu labels displayable on the display and a multi-function key having a primary function and a secondary function. Which of the key functions is selected depends on the duration of the key press. The calculating device executes the primary function if the key is pressed for a short time. However, if the key is pressed for longer than a given time period, the calculating device displays a set of menu labels and assigns a function associated with a displayed menu label to a menu key. If the key continues to be pressed, the display scrolls to show additional sets of menu labels. A menu function may then be selected by releasing the multi-function key and pressing the appropriate menu key.
