boldfontssectioning
How is it possible to remove the boldface from chapter titles, section and subsection names? I have found the following code for sections, but I can't find a way for chapters and subsections.
\makeatletter
\renewcommand\section{\@startsection {section}{1}{\z@}%
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
{\normalfont\Large}}
\makeatother
EDIT: Be sure to check the answer I provided in addition to Tobi's and Werner's answers.
Confer the Wikibooks article on Section numbering:
“To get an unnumbered section heading which does not go into the Table of Contents, follow the command name with an asterisk before the opening curly brace:
\subsection*{Introduction}. […] If you want the unnumbered section to be in the table of contents anyway, use the \addcontentsline command like this:
\section*{Introduction}
\addcontentsline{toc}{section}{Introduction}
[…]”
For more info (PDF bookmarks for the unnumbered chapters, clearing the page after
\chapters) please see the Wikibooks article.
Here are two options:
\documentclass{article}
\usepackage{sectsty}% http://ctan.org/pkg/sectsty
\allsectionsfont{\normalfont}
\begin{document}
\section{A section}
\subsection{A subsection}
\subsubsection{A subsubsection}
\end{document}
This provides a clean and understandable input. Another reference using this approach is available in Is it possible to change text color for all headings?
A patch of the section header printing macro \@sect using etoolbox:
\documentclass{article}
\usepackage{etoolbox}% http://ctan.org/pkg/etoolbox
\makeatletter
\patchcmd{\@sect}% <cmd>
{#6}% <search>
{#6\normalfont}% <replace>
{}{}% <success><failure>
\makeatother
\begin{document}
\section{A section}
\subsection{A subsection}
\subsubsection{A subsubsection}
\end{document}
This is a little obscure. The sixth argument to \@sect stems from the same argument to \@startsection - the default section-producing macro in latex.ltx. For example, here's an extract for \section, which provides as argument six \normalfont\Large\bfseries:
\newcommand\section{\@startsection {section}{1}{\z@}%
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
{\normalfont\Large\bfseries}}
The patch inserts \normalfont after every sixth argument, regardless of the section being produced.
Both options produce the output:

Depending on the class you are using there are different more or less easy ways.
If you use* KOMA-Script (which is recommended especially for german texts) you can change the
dispositionfont element:Otherwise the
titlesecpackage may helpsThe
titlesecpackage would work with KOMA-Script too …* A full working minimal working example (MWE) would have showed the class so I don’t have to guess ;-)
