I was asked to have my Introduction and Summary section uncounted. However, if I use \section* it doesn't appear in the Table of Contents which is undesired.

EDIT: The proposed solution doesn't work:

I have no idea what the 'List of figures' stands for in there.

I have implemented it just like this:

\tableofcontents
\rule[0pt]{0mm}{10pt}


Also the compilator tells me:

! Missing \endcsname inserted.


EDIT2: Of course it doesn't work. I am an idiot. Should be:

\tableofcontents
\rule[0pt]{0mm}{10pt}


If I understood you correctly then this is what you need:

% not needed for lof b/ it produces its own heading, but for your summary:
%\section*{List of Figures}
\listoffigures

• @MaK: There's no indication that the LoF should be added to the ToC (if this would be the case, I would use tocbibind package however) – user31729 Feb 16 '16 at 9:47
• @MaK: Actually I don't care whether you use \Roman, \roman, Klingon or whatever numbers for your ToC ;-) – user31729 Feb 16 '16 at 10:06
• @MaK Just a suggestion, maybe the answer would be clearer if it would not introduce unnecessary code, e.g. \section*{Summary} \addcontentsline{toc}{section}{Summary} would imho be sufficient. Otherwise someone will copy&paste it without thinking and we will see a question à la "why is the spacing after my \section*{} wrong?" – user36296 Feb 16 '16 at 17:59
