If narrowing is active in the current buffer, only export its
narrowed part.
If a region is active, export that region.
A non-nil optional argument ASYNC means the process should happen
asynchronously. The resulting buffer should be accessible
through the `org-export-stack' interface.
When optional argument SUBTREEP is non-nil, export the sub-tree
at point, extracting information from the headline properties
first.
When optional argument VISIBLE-ONLY is non-nil, don't export
contents of hidden elements.
When optional argument BODY-ONLY is non-nil, strip title, table
of contents and footnote definitions from output.
EXT-PLIST, when provided, is a property list with external
parameters overriding Org default settings, but still inferior to
file-local settings.
Export is done in a buffer named \"*Org E-Confluence Export*\", which
will be displayed when `org-export-show-temporary-export-buffer'
