## 6 Folding in Latex-Suite

Okay, we have typed enough. At this stage, hopefully, your file is looking something like this:

      1 %        File: sample.tex
2 %     Created: Sun Jun 22 04:00 PM 2003 P
3 % Last Change: Mon Dec 15 07:00 PM 2003

5 \documentclass[a4paper]{article}

7 \usepackage[sumlimits,]{amsmath}
8
9 \begin{document}
10 $$11 \label{eqn:euler} 12 e^{j\pi} + 1 = 0 13$$
14 This is the famous euler equation. I
15 will type another equation, just as
16 true:
17 $$18 \label{eqn:simple} 19 1 + 1 = 2 20$$
21 This is my contribution to mathematics.
22 \end{document}


In normal mode, press \rf. This will fold up the entire file and you should see the file looking as below:

      1 %        File: sample.tex

What has happened is that Latex-Suite folded away blocks of LaTeX code into folded regions. You can open and close folds by using the command za in normal mode.
