An interactive tabular display system having thin membrane switches positioned on the display surface around the periphery. The switches are categorized as select or function depending on the particular application software program in use. Touching one of the select switches causes a cursor to be displayed in the row adjacent to that switch; automatically, the cursor incrementally advances across that row sequentially underlining data items. When the switch is opened, the data item underlined is displayed in reverse video and additional data related to that item is displayed elsewhere on the display. The switches are provided with backlighting to provide illuminated touch points for use in dimly lit operational rooms.
