Making a Scenario Active
An active scenario on the Shelf is one being displayed by the current View. Each View may show a different number of scenarios depending on its purpose.
A View accesses the list of scenarios on the shelf from left to right. By re-ordering the scenarios on the shelf you can promote a scenario so that it becomes one of the scenarios being displayed by the View. Most Views show a single scenario only, so the first (left-most) position on the shelf is the active one and any scenario moved into this position will then be displayed by that View.
