Using Diagram Navigator and Objects panel
To navigate within the large diagram, use the Navigator tool available on the Navigation bar. It allows you to see the whole diagram in a reduced scale and to perform a number of operations over the diagram objects.
A mouse click in the Navigator area sets the center of the visible diagram area. The area currently visible in the main diagram area is outlined in a red bounding rectangle.
Right-click an item within the list to call the context menu allowing you to:
find the selected object in the diagram (if the object is found, it will be highlighted in the diagram area);

select the sorting mode applied to the objects in the list: by schema, name / by type, schema, name / by name, schema / by type, name, schema;
refresh the list.
