Software and graphical user interfaces for controlling a personal computer system using one or more switches, or alternative pointing devices. When a highlight or a cursor is over a desired display item, a fill indicator is displayed. The fill indicator provides a visual indication of how long the highlight or cursor are colocated with the item. A selection of the item is made by either the user activating a switch(es) or a fill indicator reaching a limit.
