Escape individual underscore?

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

I don't think so.

FWIW, I always set

#+OPTIONS: ^:{}

in my files. That allows me to use a_b  for the majority of my use
cases, but still allows {subscripts} in the rare cases when I need them.

I'm not sure how useful it would be but maybe there should be a setting
to accommodate the inverse case: mostly subscripts a_b but allow literal
underscores using some additional markup.

You can use \under entity, e.g.,

  a\under{}b

You could set the following, then:

--8<---------------cut here---------------start------------->8---
  ;; Interpret "_" and "^" for export when braces are used.
  (setq org-export-with-sub-superscripts '{})
--8<---------------cut here---------------end--------------->8---

Best regards,
