Cross References

Cross references are a type of hyperlink, but we want to make the point that they’re incredibly useful for print publishing. We think that they’re great for entering text, which is why we’ll talk about them in this chapter, rather than in Chapter 13, “Interactive Documents.”

Cross references give you a way to insert a marker (which Adobe calls the “source cross reference”) in text that refers to another piece of text (which Adobe calls the “destination text”). We’ll refer to these two things as the “marker” and “destination,” respectively. When the destination changes, the marker can change.

This is a feature that is particularly dear to our tiny hearts, because it means that we can finally number the figures in this book automatically, rather than doing it manually.
