# fancyhdr \leftmark, \rightmark entry for \section*

I have the following latex document and I want to include a section "List of Abbreviations" without a numbering. This should appear in the table of contents as well (it should look similar to the List of Figures and List of Tables sections). So far so good, I managed to do it with the \addcontentsline{toc}{section}{List of Abbreviations} command.

However, I still have a problem with \fancyhdr and the \leftmark option. It still lists CONTENTS in the header of the List of Abbreviations section. How can I fix this?

\section* does not write to the headers, you have to do that by hand. Add
\markboth{List of Abbreviations}{List of Abbreviations}
