You can add keywords to namable elements such as objects, clusters, materials, image clips, and so on. This allows you to classify and identify elements according to any criteria you choose. You can use these keywords in your own customizations, such as custom filters.
In addition to the procedures described in this section, you can also search for objects by keyword as described in Finding Elements by Keyword [Interface and Tools].
You can display keywords on objects in the 3D views:
To toggle the display of keywords for selected objects in a single view, choose User Keywords from that view's Show menu (eye icon).
For other ways of setting this and other display options (in specific or all views, for selected or unselected objects, and so on), see Displaying Types of Elements and Other Data [Viewing and Playback].
