Hello,

I wanted to replace the cross with a tick (or any arbitrary 
symbol) in beamer/latex exports.

I took a look at `org-latex-item' which uses the :checkbox 
property to transcode between org and latex/beamer. Looks like I 
could change the :checkbox property to enable a custom checkbox, 
but this may break other backends.

As an alternative, redefining \boxtimes works as shown below:

#+begin_src org
#+TITLE: MWE
#+OPTIONS: H:1
#+LATEX_CLASS: beamer
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) 
 %4BEAMER_col(Col) %8BEAMER_opt(Opt)
#+BEAMER_THEME: default
#+BEAMER_COLOR_THEME:
#+BEAMER_FONT_THEME:
#+BEAMER_INNER_THEME:
#+BEAMER_OUTER_THEME:
#+BEAMER_HEADER: 
 \renewcommand{\boxtimes}{\makebox[0pt][l]{\hspace{0.1em}\checkmark}$\square$}%

* Sample heading

- [X] Completed
- [ ] Trans
- [ ] 
#+end_src

This isn't optimal as the original \boxtimes is now unavailable.

Suggestions welcome.
