ABSTRACT:
The method comprises displaying menu labels (28) on a display screen (30) in proximity to an adjacent row (34) of keys of a keyboard (22), defining keys within the row (34) to match the menu labels (28), and displaying an annunciator (42) on the display screen (30) between each menu label displayed and matched key to indicate the matching of the label with key. To further assist the user in selecting the desired key, keys within the row (34) that are not matched are disabled and an error annunciator (44) appears if an unmatched key is pressed. Alternatively, unmatched keys may be allowed to execute functions not related to the displayed menu labels. The apparatus for accomplishing the method is included within a calculator (20) and comprise a programmed microprocessor (14), a top row (34) of keys for executing the labeled functions, and an LCD display screen (30) for displaying the menu labels (28) and annunciators (42, 44).
