1. LaTeX and subsubsubsections

    Normally, it should not be necessary to use a fourth structure level in documents. Unfortunately I’m forced to by some formality at my university.

    When using LaTeX and an article class ­— scrartcl in my case — there is no \chapter command available, so all enumerated sectioning commands left for you are \section, \subsection and \subsubsection.

    Changing \paragraph to behave like a \subsubsection, however, is not that difficult and yields the desired result. All it takes are these lines in your preamble:

    \usepackage[noindentafter]{titlesec}
\addtocounter{tocdepth}{1}  % Increase maximum TOC level by one
\addtocounter{secnumdepth}{1}  % Increase maximum section level by one

% Make paragraphs behave like subsubsections
\titleformat{\paragraph}[hang]{\sf\bfseries}{\thetitle\quad}{0pt}{}
\titlespacing{\paragraph}{0pt}{1em}{0.5em}

    This is the result I achieved with this solution:
