The Document Outline makes it easy to instantly jump from the hierarchical element view directly to the underlying code for an item. If an item is currently being edited in the designer/code window, it is highlighted within the outline tree. Conversely, selecting an item within the outline view causes the item to be selected/highlighted within the designer/code window. Each project type has slightly different behavior within the Document Outline tool. In general, you can use drag-and-drop actions within the tree view to move elements around in the outline. Windows Forms applications actually have a toolbar you can use within the Document Outline window. Table 5.11 describes the toolbar buttons.
