The maps themselves in version 1 and 2 of QuickSet are simple bitmaps. This has several implications for its use. Zooming is accomplished through simple pixel doubling, and maps must be opened explicitly and are by definition finite in size. Enabling coupling on a QuickSet user interface instructs it to accept shared ink messages , opening , zooming and panning commands, and view information from any other coupled user interface.
Objects are always shared.
AUTH identifies the interface and is defined elsewhere. If left unbound, any connected user interface that has enabled coupling will zoom by the appropriate factor . The factor should be a number divisible by 2. Negative numbers indicate that the map should zoom out rather than in. TIME is used by QuickSet's multimodal system to indicate when the zoom command was generated, so that if there is ink from that command still on the interface, it can be erased by the map.
