Right you've got a table of all the div elements.

The table is indexed by the title children: I can retrieve a div from
the table using the value of the title child of the div element.

The table of div elements indexed by their titles is named "titles".

The second param says that you use the value of the current element to
look up the div element that you are trying to find. If you instead had

<divref ref="Expressions"/>

you would instead use

  keyref('titles', @ref)
