I just realized that my previous question may be unclear due to some errors
in my previous post...
ERT in mathed seems to have a few issues. One of them is that LyX
determines when to end an ERT sequence. For example, if I hit C-L (to start
ERT) and then hit the underscore character, LyX exits out of ERT mode, and
the TeX produced is "\_". Although it's not relevant to my example, I often
want to be able to ERT more than just the one character. I'm currently
having issues because of the backslash that LyX adds.
Now comes my original motivation. I'm trying to use xypic in LyX. I want
to produce the following code:
\ar@/_/[r]
By omitting the underscore, I can produce
\ar@//[r]
by typing this literally. When I type the underscore literally, LyX
produces
\ar@/_{/}[r]
which doesn't work. If I try to use ERT, I get
\ar@/\_/[r]
which doesn't work because of the extra backslash.
My apologies for the double-post. I hope this clarifies things. Thanks!

Hello, I'm trying to use ERT in math mode, but as soon as I hit an escape
character, it exits ERT mode.
More specifically, I'd like to second H. Peter Gumm's question (28-Oct-05).
I'm trying to make ERT for xypic, but I can't get the /_/ part of
\ar@/^/[r]
to render properly. If I type it directly, LyX seems to insist on rendering
it as /_{/} which makes it complain. If I try to use ERT, LyX automatically
puts a \ character before the _.
Any advice would be greatly appreciated. Thanks!

Hopefully I can be helpful by explaining a few tricky things I discovered
about using xypic in LyX.
To prevent errors when using the @ symbol, I had to add
\makeatother
to the preamble, in addition to the standard
\input xy
\xyoption{all}
You can create an xymatrix in math mode by typing \xymatrix. The resulting
matrix will be 1x1, so to enlarge it, use "M-m w i" and "M-m c i" to add
rows and columns.
