The Thematic Key window displays details of:
- current data flags available in the database
- network object symbols on the GeoPlan window
- current themes on the GeoPlan
You can display the Thematic Key window by clicking the Thematic Key Window iconon the Docking Windows toolbar or choosing Thematic key window from the Window menu. The button and menu item toggle the display of the window, so clicking either again will hide the Thematic Key window.
The Thematic Key window is a dockable window, so you can move it to a different edge of the workspace, or leave it floating. See Using dockable windows for more on dockable windows.
One suggestion to save space would be to move the Thematic Key window from its default position on the right side, and dock it below the Model Group window on the left.
