This screenshot shows the Variables editor tab in a fragment. The editor contains a warning at the top of the tab that reminds you that you're extending a fragment.

In this image, the editor tab lists two constants. The Properties pane shows the properties of the constant selected in the list:

• the name and description of the constant
• the dependency where the constant is defined
• a dropdown list for selecting the Default Value for the constant
• a list of components where the constant is used.
