Notwithstanding this case, if `org-element-at-point' returns
`special-block', you /know/ that you are either on block boundaries
(#+begin_special or #+end_special) or on any affiliated keyword above,
but /never/ within the block.

If `org-element-at-point' returns `special-block' here, you create an
exception, which you have to handle later on.

Besides, the truly empty contents are

  #+begin_special
  #+end_special

therefore, I'm not shocked if

  #+begin_special
  
  #+end_special

is a special block with an empty paragraph instead.

Hi Nicolas,

Thanks for the helpful reply.

Out of curiosity, why is it "more" consistent to return paragraph here?

That's very cool.  Thanks.

This is a corner-case. `org-element-at-point' returns the closest
element at point, but prefers to see an empty paragraph than a special
block, for consistency. I.e., when point is within block boundaries, you
never return `special-block'.

(org-element-lineage (org-element-at-point) '(special-block) t)

[O] org-element-at-point and special blocks

[Rasmus]

Hi,

Is there a reason why org-element-at-point reports the type to be a
paragraph for special blocks?  E.g. in the examples at the bottom of this
mail, where | is the cursor, the types are: export-block, src-block and
paragraph with a nested special block.

Is there a neat way to detect if point is inside a block?  I’m trying to
write a function for structures (e.g. #+begin_latex) that works like
org-babel-demarcate-block.

Thanks,
Rasmus
