    • 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).
    • 该方法包括在靠近键盘(22)的相邻行(34)的邻近行(34)的显示屏幕(30)上显示菜单标签(28),在行(34)内定义键以匹配菜单标签(28) ,并且在显示屏幕(30)上的每个菜单标签显示和匹配键之间显示信号器(42),以指示标签与键的匹配。 为了进一步帮助用户选择期望的键,禁用行(34)内的不匹配的键,并且如果按下不匹配的键,则出现错误信号器(44)。 或者,可以允许不匹配的键执行与所显示的菜单标签无关的功能。 用于完成该方法的装置包括在计算器(20)内并且包括编程微处理器(14),用于执行标记功能的键的顶行(34)和用于显示菜单标签的LCD显示屏(30) (28)和信号器(42,44)。
