== Behaviour ==
=== Drag and drop ===
You may drag and drop the object / fact types onto diagram windows to visualize the information structures.
=== Statusbar ===
The statusbar will show the total number of object / fact types, including any hidden items (due to defined filters).
=== Diagram highlighting ===
The combobox at the bottom left enables you to dim already displayed object / fact types. You may set this highlighting or dimming to one of the following options:
* Active repository. None are dimmed
* Any diagram. Only otft's are dimmed which are in any of the opened diagrams.
* Active diagram. Only dim otft's which are in the diagram currently active.
* All diagrams. Dim all otft's which are on any diagram in the project.
=== Shortest path ===
Since v8.1 the shortest path can be determined. This is a feature which will only work using the following procedure:
* select only two object / fact types
* use the context menu and choose "shortest path"
* all items on this path are added to the selection
It is useful by dragging this newly calculated selection into a diagram for viewing purposes.
