You say, I do not need to load it?


No. Why do you think you should? The note only say it needs to be
installed, not manually loaded.

However, I could not find \usepackage{mhchem} in this helpfile
Math.lyx
Is this intentional? Or included in another \usepackage?


I see in the source preview of this manual:

\PassOptionsToPackage{version=3}{mhchem}
\usepackage{mhchem}

Note that mhchem is loaded automatically. Did you only look in the user
preamble?


Yes, Jürgen. I wanted to make sure that mhchem is working.
You say, I do not need to load it?

Fwd: missing \usepackage{mhchem} in helpfile Math.lyx

2022-04-02 Thread Wolfgang Engelmann via lyx-users



In the helpfile Math.lyx it is stated:

To export this document to PDF, PS or DVI the LaTeX-packages braket, 
cancel, eurosym, mathdots, mathtools, mhchem, undertilde and was should 
be installed. If they are not installed the document can be exported 
anyway but the sections where the packages are required will not appear 
in the output. An exception is mhchem; if it is not installed, this file 
cannot be exported.


The latest PDF-version of this document can be found 
here:https://wiki.lyx.org/LyX/Manuals#Math


However, I could not find \usepackage{mhchem} in this helpfile Math.lyx
Is this intentional? Or included in another \usepackage?
