Point Symbol Analogous to Section Marker

Question

Is there a standard typography symbol for point used to reference a preceding list, analogous to the section marker §? Conceptual example:

As to •3 above...

Answer 1

I don't know of a standard typography symbol for "point" and, as Marco has pointed out, using such a symbol might result disruptive and could produce ambiguity (since it's a non-standard convention). That said, you could use the cleveref package to redefine, in an automated way, the label used to cross-reference the items in a list. In the following example I illustrate the standard label used by cleveref for the first-level items of an enumerate environment, and show two new options using \textbullet, and \textopenbullet (the latter from the textcomp package).

I'd rather sacrifice brevity for clarity and use the standard words "item" or "items" (and their upper case variants), but it's up to you to use some symbol.

\documentclass{article}
\usepackage{textcomp}
\usepackage{cleveref}

\newcommand\ItBu{
  \crefname{enumi}{\textbullet}{\textbullet}
  \Crefname{enumi}{\textbullet}{\textbullet}
}

\newcommand\ItOBu{
  \crefname{enumi}{\textopenbullet}{\textopenbullet}
  \Crefname{enumi}{\textopenbullet}{\textopenbullet}
}

\begin{document}

\begin{enumerate}
  \item First item.\label{firsta}
  \item Second item.\label{seconda}
  \item Third item.\label{thirda}
\end{enumerate}

\cref{thirda}

\cref{firsta,seconda}

{
\ItBu
\begin{enumerate}
  \item First item.\label{firstb}
  \item Second item.\label{secondb}
  \item Third item.\label{thirdb}
\end{enumerate}

\cref{thirdb}

\cref{firstb,secondb}
}

{
\ItOBu
\begin{enumerate}
  \item First item.\label{firstc}
  \item Second item.\label{secondc}
  \item Third item.\label{thirdc}
\end{enumerate}

\cref{thirdc}

\cref{firstc,secondc}
}

\end{document}

Answer 2

You may be interested in the following symbols, which all operate in text mode:

\textbullet 
\textperiodcentered (may be too small, but you appear to 
   reference it in your question)
\textopenbullet (requires loading the "textcomp" package)

These three symbols look like this:
