Sectioning commands provide the means to structure your text into units:
\part
\chapter
\section
\subsection
\subsubsection
\paragraph
\subparagraph
All sectioning commands take the same general form, e.g.,
\chapter[toctitle]{title}
In addition to providing the heading title in the main text, the section title can appear in two other places:
You may not want the same text in these places as in the main text. To handle this, the sectioning commands have an optional argument toctitle that, when given, specifies the text for these other places.
Also, all sectioning commands have *
-forms that print
title as usual, but do not include a number and do not make an
entry in the table of contents. For instance:
\section*{Preamble}
The \appendix
command changes the way following sectional units
are numbered. The \appendix
command itself generates no text
and does not affect the numbering of parts. The normal use of this
command is something like
\chapter{A Chapter} ... \appendix \chapter{The First Appendix}
