Thanks for your help. This sort-of works. There seems to be some errors
with a simple file. Here are my steps:
1) File -> New
2) Insert -> Math -> Display Formula. Cursor should be inside math box.
3) Type "\split" then a space
4) Edit -> Tabular -> Add Column
5) Edit -> Tabular -> Add Row. There are now 4 math boxes.
6) Fill the boxes with characters (I used letters "a", "b", "c", "d")
7) View -> DVI
There are 4 errors generated. I exported the document to a LaTeX file to
try to fix the errors. The two steps I took to fix this are:
1) added: \usepackage{amsmath}
2) commented out: \newcommand{\boldsymbol}[1]{\mbox{\boldmath $#1$}}
(since this is definedin amsmath).
I notice that if I start a fresh LyX file, and I use one of the menued APS
features (for example the AMS gather Environment), the resulting exported
LaTeX file has the \usepackage{amsmath} included and the
\newcommand{\boldsmbol} is not included.
So, when someone uses \split inside Math Display made, shouldn't LyX
be making sure that \usepackage{amsmath} is included?
Thanks,
Fred
