\begin{appendix}
\section{superuser}
\dots{}
....


Shows up as

A       superuser            11

in the \tableofcontents.

Unfortunately, I have to use a different style: the appendix is not to show up in the table of contents, but in a separate listing right before the appendix.

I see the following options to solve this:

• suppress output in tableofcontents and somehow recreate the part on a different page
• generate a custom listing of specified / the following section

I use scrartcl as document class.

Does the solution in tex.stackexchange.com/questions/8211/list-of-appendices not help? –  TH. Jan 7 '11 at 9:58
Also, \appendix isn't an environment, but a macro that you put before your first appendix. –  TH. Jan 7 '11 at 10:00
I searched superuser and got pointed here, but forgot to search again. Thanks for the link and the clarification env. vs. macro! –  None Jan 7 '11 at 11:29
So does the link TH gave you answer your question? Then we can close this question as a duplicate. –  Hendrik Vogt Jan 7 '11 at 13:37
I'm taking my vote to close back, since the linked question only asks about a specific non-standard document class. –  Caramdir Jan 7 '11 at 17:03

A somewhat hackish way to get a list of appendices in scrartcl is to add the following at the start of the appendix:

\appendix
% Set the name for the list of appenices
\newcommand\listoftoaname{Appendices}

\let\oldlistoftoc\listoftoc
\renewcommand\listoftoc[1]{\oldlistoftoc{toa}}
\tableofcontents
\let\listoftoc\oldlistoftoc

% we will now redefine the sectioning commands so that that put entries
% into the list of appendices. The redefinitions are rather simplistic
% and break the starred versions and the optional argument.
% Thus the redefinitions have to be added after the \tableofcontents call.

\let\oldsection\section
\renewcommand*\section[1]{%
\oldsection{#1}%
}
\let\oldsubsection\subsection
\renewcommand*\subsection[1]{%
\oldsubsection{#1}%
}
\let\oldsubsubsection\subsubsection
\renewcommand*\subsubsection[1]{%

For scrreprt and scrbook, you need to add an analogous redefinition for \chapter. As the redefinition of the sectioning commands are rather simplistic, they break the starred versions and the optional argument. Thus before any starred sections (like the bibliography), you should revert the redefinitions with \let\section\oldsection.
