I want inline subsubsection headings, as displayed in the example below. It is easy to realize them with the titlesec package, but according to this thread, there are incompatibilities between KOMA and titlesec.
Is there a solution which does not use titlesec and is fully compatible with the KOMA classes?
MWE:
\documentclass{scrbook}
\usepackage{blindtext}
\usepackage{titlesec}
\titleformat{\subsubsection}[runin]{\bfseries}{}{}{}[.]
\begin{document}
\chapter{A chapter heading}
\section{A section heading}
\subsection{A subsection heading}
\blindtext
\subsubsection{Inline subsubsection heading}
\blindtext
\subsubsection{Another inline subsubsection heading}
\blindtext
\end{document}
and a screenshot:


KOMAandtitlesec, as written in the manual, but it's basically ignored ;-) – Feb 17 '15 at 10:51
