Org Mode Latex Export Customization of org-export-latex-emphasis-alist

[Gaurav Sharma <gvshar@gmail.com>]

Hello!

I am a relative newbie to Org even though Emacs has been my editor of
choice for a long time. I'm trying to customize the
org-export-latex-emphasis-alist by using the following in my .emacs

(setq org-export-latex-emphasis-alist (quote (("*" "\\textbf{%s}" nil)
("/" "\\emph{%s}" nil) ("_" "\\alert{%s}" nil) ("+" "\\st{%s}" nil)
("=" "\\verb" t) ("@" "\\alert{%s}" nil) ("!" "\\note{%s}" nil) ("~"
"\\verb" t))))

Several of the above re-definitions seem to take effect. In fact, in
the above "_" is redefined to be the same as "@" for testing that the
re-definition is indeed effective and I have verified that it is.
However, the definitions of "@" and "!" do not seem to take effect at
all. I see the same behavior when I customize this variable through
the Org->customize interface. I've tried a lot of things and am at my
wits end in terms of figuring out this weird behavior.

I would very much appreciate if someone could shed more light on this.
My initial thought was whether there could be a dependency on latex
packages that make alternate use of these special symbols. However,
that should come into play only in the latex file and upon seeing the
latex file I see that indeed the definitions of "@" and "!" seem
ineffective. In case it matters, I am working with a org file intended
for use with beamer that is included below.

Suggestions for a fix would be very helpful.

Thanks much in advance for your help,

-- Gaurav
