The external header begins with the text "Usage",
followed by the name of the selected object.

Three "Show" checkboxes control the information to be displayed below.

    show [[{{#var:G}}Disjoint_Class|disjoint classes]]

At the top of the display area, there is a summary line of the form
"Found <count> uses of <data item>".
