Abstract
An intuitive operator panel for machines is provided. A listing of possible functions on a transparent face is located adjacent to each multiple function control or display. A colored background viewable through the transparent face, reduces the readability of the items in the list. A moveable opaque field is located between the transparent face and colored background and increases their readability. The opaque field can be moved by the operator to highlight a desired function from the list. The desired function is highlighted in the list and the machine senses the opaque field's position to determine the function selected. Such a configuration reduces the visual clutter associated with function lists which accompany multiple function controls or displays.
