The default user interface provided for the Lotus® Expeditor is similar in appearance and action to other user interfaces, such as Microsoft® Windows®, Macintosh, and Motif. Users employ a "selection/action" model to interact with it.
In a selection/action model, selection pertains to each view and is independent of other selections in other views. The view retains what is called selection memory. For example, when a user selects one or more items in a list in one view, and goes to a different view (in a different plug-in or the same one), and then returns to the list in the original view, the selected items are still selected. This selection model helps users remember where they were and what they were doing in the view.
Inactive selection refers to the display of a previous selection at the same time that the active selection is displayed. All actions only take place on active selections, but continuing to display the inactive selection helps users remember the choices they have made.
