Hello,

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.
