ContentMap shows document elements, structural nodes (entity and XInclude borders), processing instructions and comments, and also positions between them.
When you move the mouse pointer over ContentMap items, they get highlighted to better demonstrate the position in the document tree, and tooltips pop up showing attributes of elements and items' text.

Occurrences of a particular element
In addition to its actual location, an element can occur in the document multiple times depending on the stylesheet and document view. For example, titles of Docbook sections can also be displayed in the Table of Contents at the beginning of the document or in grey draft areas.
To go through all occurrences of a particular element in the document, find the element in the ContentMap and keep clicking it.
