Expanding and Collapsing the Browser Tree

The current model's hierarchy is visible in the tree structure of the browser window:

• A plus (+) sign next to an icon indicates that the icon is collapsed; that is, it contains other model elements. Click the + sign to expand the icon and view its subordinate items.
• A minus (-) sign next to an icon indicates that the icon is fully expanded. Click the minus (-) sign to collapse the item.
