A keyboard assembly incorporating multiple lighting modalities is disclosed herein. In one lighting mode, discrete indicator lights are embedded in the actuator keys to signify the state of an associated function. In a second mode, a plurality of legends, each sufficiently proximate to an associated function actuator key, are illuminated. In accordance with one embodiment of the present invention, function indicator lights in the actuator keys provide real-time user feedback such that scrolling through numerous display screen menus to determine availability of a desired function may be eliminated. Further, the backlit actuator legends enhances usability of system in low light clinical environments during ultrasound exams making the function actuator keys easy to locate. In addition, the backlit legends increases the contrast in high ambient light environments for improved readability. The combination of design features disclosed provides a relatively inexpensive, long lasting keyboard assembly that provides improved user feedback for more efficient operation.
