Using hyperlinks

Initially, LaTeX was used primarily to produce high-quality prints on paper. Since the output was device-independent from the beginning, the results can also be viewed on screens, tablets, and smartphones.

With electronic publishing, we gain access to convenient functionalities, most notably hyperlinks, enabling effortless navigation within documents. This recipe focuses on using LaTeX to incorporate hyperlinks into a PDF.
