reftex: Labels and References

 
 3 Labels and References
 ***********************
 
 LaTeX provides a powerful mechanism to deal with cross-references in a
 document.  When writing a document, any part of it can be marked with a
 label, like ‘\label{mark}’.  LaTeX records the current value of a
 certain counter when a label is defined.  Later references to this label
 (like ‘\ref{mark}’) will produce the recorded value of the counter.
 
    Labels can be used to mark sections, figures, tables, equations,
 footnotes, items in enumerate lists etc.  LaTeX is context sensitive in
 doing this: A label defined in a figure environment automatically
 records the figure counter, not the section counter.
 
    Several different environments can share a common counter and
 therefore a common label category.  For example labels in both
 ‘equation’ and ‘eqnarray’ environments record the value of the same
 counter: the equation counter.
