NEPTUNE

### Edit heading levels

For inserting a new section or any other sectional heading, standard LATEX commands can be used. An example of the code is provided in the below verbatim:

\section{A New Section}
\xlabel{sec30}
Using standard \LaTeX{} commands, one can create a
new section while editing a document in Neptune.

Slightly modified \xlabel{...} is used in place of \label{...} with the same functionality. In the same vein, \xref{...} takes the role of \ref{...}. The cross-ref command, \xref{...} accepts more than one label as its argument and the output will be sorted and compressed if needed.
