A user input having a first mode of operation relating to the entry of a command is indicated on a display device prior to the actual execution of the command, afterwhich a second mode of operation may be entered wherein the command is actually executed using the displayed information for confirmation purposes. In a preferred embodiment, the user input device takes the form of a hand-held remote-control unit, and the display is a television monitor. In this case, the invention is operative to determine the position of a user's finger relative to one or more keys of the keypad on the remote-control unit, and display, on the TV monitor, information relating to the user's relative position. For example, the display might show textual information relating to the pushbutton in closest proximity to the user's finger or, alternatively, the display may show a graphical representation of at least a portion of the keypad, along with an icon that moves relative to the graphical display in relation to movements made by the user.
