Escape individual underscore?

Hi List,

I want to include a literal underscore in LaTeX export, like FOO_BAR. Right
now I get:
FOO$_{\text{BAR}}$

Contrary to this stackexchange question
<http://stackoverflow.com/a/12753930/3371623>, if I try to escape the
underscore with a backslash, I get:
FOO$\backslash$$_{\text{BAR}}

I've found that I can set org-export-with-sub-superscripts to "{}" to avoid
this problem, but I'd rather escape individual underscores on a case by
case basis. Is this possible?

As an aside, section 11.7.2 of the org info says "Configure the variable
`org-use-sub-superscripts' to
change this convention." Fortunately the docstring for
org-use-sub-superscripts points out that display and export functionality
are now controlled by separate variables. I would propose a patch to update
the info to clarify that two variables are used, but I'm not currently set
up to do so.

Regards,
Jake
