Using hyperlinks and bookmarks

There's a sophisticated package called hyperref that does nearly all basic hyperlinking automatically. Let's check it out.

Adding hyperlinks

We shall load the hyperref package and inspect its effect:

1. Open the preamble.tex file, which we used in the previous chapter. At the end, add this line:

   \usepackage{hyperref}

2. Save this document under the same name.
3. Open our Book of Equations from the previous chapter; we called it equations.tex.
4. Compile the document twice without making any changes. Let's see how the document now appears; here, we can see red boxes indicating hyperlinks:

Figure 12.1 – A table of contents with hyperlinks and bookmarks

Cross-references, such as references to equation numbers, also have red boxes:

By just loading the hyperref package, our document has significantly changed...
