How do I open the Highlight Settings dialog box?
In the Object Explorer, select Highlighting on and click Settings.
Use the Highlight Settings dialog box to highlight specified objects on the graphic display and the Object Explorer tree list.
You can select objects by object type, animation type, or tag name.
Objects with the selected properties are highlighted in red on the graphic display and in the Object Explorer. If your graphic display uses a red background, you will not be able to see the highlights.
