Changing the headings

Like in our diagram example, if you don't like the heading Contents, you could easily change it. The text of the heading is stored in the text macro \contentsname. So, just redefine it as follows:

\renewcommand{\contentsname}{Table of Contents}

Here's a list of all those headings:

List	Heading command	Default heading
Table of contents	\contentsname	Contents
List of figures	\listfigurename	List of figures
List of tables	\listtablename	List of tables
Bibliography	\bibname in book and report \refname in article	Bibliography in book and report References in article
Index	\indexname	Index

Furthermore, as promised, here's a list of further macros for names used by LaTeX:

Name	Command	Default value
figure	\figurename	Figure
table	\tablename	Table
part	\partname	Part
chapter	\chaptername	Chapter
abstract	\abstractname	Abstract
appendix	\appendixname	Appendix

Not really surprising! Using name macros is especially useful when another language...
