Hi Nicolas and others,

org-e-beamer exports *bold markup* as \alert{..}. I was wondering if
there is a way to export it as the usual \textbf{..}. I would also like
to have a convenient markup for \structure{..}, how do I add new markup?
It would be okay if I could alter existing markup to be exported as
\structure{..}; then I could use one of the less used ones. I saw there
is a defcustom, org-e-latex-text-markup-alist, for org-e-latex; but I
couldn't find a similar variable for org-e-beamer.

Thanks for any inputs.

You can't add new markup.  

Though, there are already 4 symbols used for regular text and 2 for
verbatim text.  And you have full control over their output with
filters.

So, let's say "*" will produce \textbf{...} and "+" will produce
\structure{...}.

#+BEGIN_SRC emacs-lisp
(defun suvayu-beamer-bold (contents backend info)
  (if (not (eq backend 'e-beamer)) contents
    (replace-regexp-in-string "\\`\\\\[A-Za-z0-9]+" "\\\\textbf" contents)))

(defun suvayu-beamer-structure (contents backend info)
  (if (not (eq backend 'e-beamer)) contents
    (replace-regexp-in-string "\\`\\\\[A-Za-z0-9]+" "\\\\structure" contents)))

(add-to-list 'org-export-filter-bold-functions 'suvayu-beamer-bold)
(add-to-list 'org-export-filter-strike-through-functions
             'suvayu-beamer-structure)
#+END_SRC

You can also derive a new back-end from e-beamer that will behave
differently for bold and strike-through object types.

Your example below works wonderfully. However I have a question, for the
sake of understanding.

I do not understand the above regular expressions. I guess \\` to match
the start of string (one extra backslash is required to escape the 2nd).
But I don't understand the four backslash sequence; I guess it inserts
\\ to the string, but why is that necessary?

Thanks a lot for the pointers.

See LITERAL optional argument (which is nil here) in `replace-match'
primitive.
