-Call the @code{org-list-insert-radio-list} function to insert a radio list
-template in HTML, @LaTeX{}, and Texinfo mode documents.  Sending and
-receiving radio lists works is the same as for radio tables (@pxref{Radio
-tables}) except for these differences:
-
-@cindex #+ORGLST
-@itemize @minus
-@item
-Orgstruct mode must be active.
-@item
-Use @code{ORGLST} keyword instead of @code{ORGTBL}.
-@item
-@kbd{C-c C-c} works only on the first list item.
-@end itemize

-Built-in translators functions are: @code{org-list-to-latex},
-@code{org-list-to-html} and @code{org-list-to-texinfo}.  They use the
-@code{org-list-to-generic} translator function.  See its documentation for
-parameters for accurate customizations of lists.  Here is a @LaTeX{} example:
-
-@example
-% BEGIN RECEIVE ORGLST to-buy
-% END RECEIVE ORGLST to-buy
-\begin@{comment@}
-#+ORGLST: SEND to-buy org-list-to-latex
-- a new house

-@kbd{C-c C-c} on @samp{a new house} inserts the translated @LaTeX{} list
