LaTeX tricks

Here are some tricks I have found for LaTeX. This section will be updated from time to time.

## Changing fonts size

If you are using the article class for instance, three different font sizes are available : 10,11,12 pt. You can use it like this :

\documentclass[10pt]{article}

What if you want to use to other sizes ? Pre-built functions like do not work on the section titles. The solution is to redefine fontsize:

\documentclass{article}
\begin{document}
\tiny
\def\fontsize#1#2{}
This is a test (hey,hey).
\section{One}
This is a test (hey,hey).
\end{document}
