Updated with MWE:
I am making a template for keeping track of articles for a project and for this I want to have costumized \cite-s to use in text and as section titles. I have made a crude solution:
\documentclass[a4paper,13ptmathspec]{scrartcl}
\usepackage{filecontents}
\usepackage{biblatex}
\begin{filecontents}{ref.bib}
@article{szabo2006,
title = {Phase transition in the collective migration of tissue cells: Experiment and model},
author = {Szab\'o, B. and Sz\"oll\"osi, G. J. and G\"onci, B. and Jur\'anyi, Zs. and Selmeczi, D. and Vicsek, Tam\'as},
journal = {Phys. Rev. E},
volume = {74},
issue = {6},
pages = {061908},
numpages = {5},
year = {2006},
month = {Dec},
publisher = {American Physical Society},
doi = {10.1103/PhysRevE.74.061908},
url = {http://link.aps.org/doi/10.1103/PhysRevE.74.061908}
}
\end{filecontents}
\addbibresource{ref.bib}
\begin{document}
\section{First section}
I want to be able to modifiy the citing style separatly here (\citeauthor{szabo2006} \citeyear{szabo2006}\cite{szabo2006}).
\section{\citeauthor{szabo2006}:\citetitle{szabo2006}\cite{szabo2006}}
and in the section title. I also don't want the quotes in the section title.
\printbibliography
\end{document}

My problem is, that I could make these multiple cite-s into one command with newcommand, but for example I would like to remove the quotes around the title, when I put it in the section title. It seems to me that \DeclareCiteCommand would be the way to go, but I was unable to make it work. How could this be accomplished?

\chapteror\sectionon to\MakeUppercaseand friends, you might also like to read A \cite{} as name for a chapter header. If you can come up with a MWE, we might be able to eventually answer your question satisfyingly. – moewe May 12 '14 at 05:04
