,----[ C-h v org-export-latex-hyperref-format RET ]
| org-export-latex-hyperref-format is a variable defined in `org-latex.el'.
| Its value is "\\href{%s}{%s}"
| 
| Documentation:
| A printf format string to be applied to hyperref links.
| The format must contain two %s instances.  The first will be filled with
| the link, the second with the link description.
| 
| You can customize this variable.
