ABSTRACT:
An electronic digital computer system includes a Graphical User Interface (GUI) for displaying graphical objects such as icon buttons, scrolling text lists, and text entry fields on a monitor. A keyboard includes a label key such as a conventional alternate (Alt) key which, when depressed, causes alphanumeric characters to be superimposed on the graphical objects. Depression of an alphanumeric key on the keyboard corresponding to the alphanumeric character superimposed on a selected object causes an associated operation to be launched. The GUI includes an object table having an entry for each graphical object. Each entry includes an object name, corresponding alphanumeric character, object type (e.g. icon button, text input field), and object display position. A display generator accesses the object table using the object names as inputs, obtains the alphanumeric characters as outputs, and superimposes and displays the alphanumeric characters on the objects. The alphanumeric characters are displayed at positions that are offset from the object display positions by predetermined distances and directions corresponding to the object types.
