Making clickable links to sections with hyperref

\hyperref is your friend:

\usepackage{hyperref}

%... other code

\section{Hello World}
\label{sec:hello}

\hyperref[sec:hello]{Word of text}

\hyperref does the job:

\usepackage{hyperref} % import the package

%... other code 

\section{Alice in Wonderland} % a normal section we want to link to
\label{sec:Alice} % this is the bookmark for the, links which refers to the last section

% links to the section with the variable name Alice, showing: "Some Displayed Text"
\hyperref[sec:Alice]{Some Displayed Text}

% links to the section with the variable name Alice showing the name of the Section, here: "Alice in Wonderland"
\nameref{sec:Alice}

% Links to the section with the variable name Alice showing the description of the section, here: "section 1"
\autoref[sec:Alice]{Some Displayed Text}

Hyperref builds section links automatically. You should be able to reference them as section.i where i is the section number. If you wanted to say "Section 3" and link to section 3, it would look as follows:

\hyperlink{section.3}{Section 3}

If you are prone to reorganizing your sections, this is not perfect, and I would advise using one of the above solutions, however, for relatively stable orderings, this is much simpler as it doesn't require adding a \label tag whenever you want a new section.

Testing indicates this also works for other sectioning commands like \chapter (where the reference becomes chapter.1). For nested sectioning commands like \subsection, the reference becomes subsection.1.1.

If you want to reference chapter 3 section 2 you can use the following code:

\hyperlink{section.3.2}{Section 3.2}
