Summary
In this chapter, we learned how to reference chapters, sections, footnotes, and environments by their number or by the number of the corresponding page.
Using labels for referencing, we did not need to specify a number by ourselves; LaTeX determines the correct number of a page for us, or of a section, a footnote, or an environment.
We even got to know some clever ways of context-dependent referencing.
In the next chapter, we shall deal with lists, which consist mainly of references: tables of contents, lists of figures and tables, and bibliographies.
