Using the Topology Map Controls
You can zoom in or out on topology by using the magnifying glass icons on the upper right.
There is also a "fit to screen" option that shows the entire topology in the Topology map.
The “mini-map” icon lets you see and navigate the entire topology while displaying only a portion of it using a movable thumbnail.
You can display the entire topology view in a full screen browser window by using the Print icon.
You can also export the topology view as a PNG, JPG, PDF, or SVG file.
