ENL - Understanding Default Layers

The Layers window contains three default Layers:

<Default> layer
Any objects or links (except Belongs To and Escalated links, see options below) will be automatically assigned to this Layer when you place them in the Graphical View. This Layer is displayed by default.
<Belongs To> layer
All Belongs To links are automatically assigned to this Layer. This Layer is displayed by default.
<Escalated> layer
All Escalated links are automatically assigned to this layer. This Layer is displayed by default.

Notes

You cannot remove or rename any of these three Layers.
You can assign objects and links automatically assigned to these Layers to other user defined Layers.
You cannot return Belongs To and Escalated links that have already been moved (from their default Layers to a user defined layer) back to their defaults.
If you reassign a Belongs To link to a user defined Layer, it will change color from pink to red. The properties of the link remained unchanged.
