I was using ACM CHI latex template in which sections do not have section numbers. For example:
BACKGROUND
SubBackground
SubSubBackground
Now I want to cross reference, but I don't have a section number to refer to:
\section{Background}
\label{background}
\subsection{SubBackground}
see \ref{background}
BACKGROUND
SubBackground
see
How do I cross-reference here?

\label-\refsystem using something like\makeatletter\newcommand{\setref}[1]{\gdef\@currentlabel{#1}}\makeatotherwhich allows you to use\section{Background}\setref{Background}\label{background}and then later issueSee section~\ref{background}. – Werner Aug 27 '12 at 5:25
