Now we go back to the 2000 node. We enter the section name << Jul >> into the node text where we want the << Jul >> section text to be output. When tangling, Leo will replace this section name with the section text. This operation is recursive, so if a section text contains a section name, this also will be replaced with the named section's text.

Note: when we put a << section name >> into node text, the section name must correspond to a section located under the current node. Leo only looks in subnodes for section names.
