Org-mode multi-line emphasis and bold

Question

Is there any sort of markup in org-mode to get multiple lines of text to be bold, italics, etc?

*This is what I want to be bold and I only want lines to 
be a certain length so that this doesn't work.*

---

I know about using visual-line-mode as an alternative to fill-paragraph which would solve this problem, but I like M-q too much and I want to try and keep my files at a certain width.

Snippets welcome. I don't know Elisp so I can't do it myself. But I guess this would ruin export too.

I'm thinking something like:

#+BEGIN_BOLD
  All my text in here would be super bold
  and would be very nice.
#+END_BOLD

As per the answer from nicael's comment on the question:

By default, org-mode allows a single newline. So if you want to be able to add markup to text that spans more than two consecutive lines, you'll need to modify this entry.

(setcar (nthcdr 4 org-emphasis-regexp-components) N)

... where N is the number of newlines you want to allow.

Higher up in the same answer, it says that you need to add the line:

(org-set-emph-re 'org-emphasis-regexp-components org-emphasis-regexp-components) 

after the line above.

Answer 3

org-emphasize in org-mode does this. From https://orgmode.org/worg/doc.html#org-emphasize:

Insert or change an emphasis, i.e. a font like bold or italic. If there is an active region, change that region to a new emphasis. If there is no region, just insert the marker characters and position the cursor between them.

Select the regions and then run org-emphasize with C-c C-x C-f. You will be prompted for the bracketing character to use in the emphasis (* for bold, / for italics, etc.). Entering a space removes existing emphasis.
