How to add custom markup elements and to define custom backends?

How to add custom markup elements and to define custom backends?

[Vladimir Lomov]

Hello,
sometimes I need markup elements than missing in Org mode, for example
combination of both bold and italic. Some backends, for instance html
and latex (with minor exception) support such combinations. So I wonder
1) how to define custom or new markup elements that can be used in
   backends, if it is possible
2) and how to extend or customize (write a custom backend) to take into
   accout these new elements.

Thanks in advance, Vladimir Lomov

Hi Vladimir,

Org mode does not support this directly (and to be honest, I know very few applications
where combining different attributes makes a lot of sense).

You could probably play with org-emphasis-alist and org-latex-text-markup-alist to cook something up.
but first I would think very hard about the question if this is really needed and does not create too much visual clutter.

Regards

I agree with Carsten on the last point about visual clutter.  That said,
if the OP rarely uses one of the standard mark-ups, say +strikethrough+,
then an export filter overriding the default would do just fine.  For an
example, see here:

Hope this helps,
