Using the Layer Manager
Using the layer manager, you can perform various operations related to layers and legends such as viewing and hiding map features, adjusting the transparency of the current map, zooming in to a scale within which a feature is visible, reordering layers and viewing legends.
The Layer Manager is accessed by using Map Content and Legend. To access the Layer Manager, select Map Content and Layer in the command bar.
