A numbering scheme is disclosed for implementation in the context of an application display. A user is able to select an item on the display by speaking a number corresponding to a desired control item. In some cases, the screen can include so many numbers that the user loses context and is unable to identify which number they want to select. For this reason, in one embodiment, a temporal switching mechanism is implemented wherein periodic switches (e.g., second-long intervals) occur between showing numbered items and showing a non-numbered screen. In one embodiment, an optional secondary confirmation step is implemented wherein the user sees only the item they just selected and has the chance to (a) learn the programmatic name of the item they selected and/or (b) either confirm and proceed with their selection, or cancel. In one embodiment, the optional secondary confirmation step is omitted if the user speaks a number followed by a predetermined command word.
