## Outline view - AquaLogic Service Bus

This view displays a hierarchical view, or outline, of a structured file that is currently open in the editor area. The contents of this view are editor-specific.

In ALSB, when the proxy service is editor is open and the Message Flow Editor is selected, the Outline view displays a hierarchical view of the nodes and actions in the message flow. When the Message Flow Editor is displayed, you can switch between the hierarchical view and a thumbnail view of the service, as described in the table below:

Button | Description
--- | ---
| Click this button to display a hierarchical view of the contents of the current editor.
| Click this button to display a graphical thumbnail view of the contents of the Message Flow Editor. When the entire message flow does not fit in the editor, a blue mask appears in the outline view to show what portion of the flow is visible in the editor. To display a different portion of the flow, you can drag the mask to the portion of the flow you want to display in the editor.
