The Roundabout Standard Editor is basically a tabbed dialog. The left-hand pane displays a tree view of the pages available and the right-hand pane shows the selected page.
Click the + symbol against the tree items in the left hand pane to expand the tree and see the available pages. They are grouped to assist you to find what you need.
Click on a page heading in the left hand pane to display the page on the right.
The Roundabout Properties Diagram is used to explain the terminology. Select the Diagram button to display it and click again to hide it. Clicking within different fields changes the display of the diagram to the selected parameter.
