Selecting to enter an endnote at the end of a section instead of at the end of a document.
Just as a book can be divided into chapters, a Word document can be divided into sections. If a document is divided into sections instead of being one long continuous document, you can add endnotes to the end of sections instead of having them all at the end of the document. You'll have a chance in the practice session to divide a document into sections and then to add an endnote to the end of a section.
When you insert endnotes at the end of sections, you also have the option to number the notes continuously from section to section, or to restart the numbering with each section. You'll see how in the practice session.
