Do you mean like a function maybe, that works everywhere?

(defun my-insert-string-literal (&optional string)
  "Asks for STRING if not supplied and inserts it as literal
  string with quotes."
  (interactive)
  (let ((string (or string (read-string "String: "))))
    (insert (prin1-to-string string))))

thing-at-point would need to be defined, I would not know now how
to define it universally to find out string with quote on both
sides and that it works over new lines.

"Some string✗ here \"Mo✗re\" and more."
"Then again✗ maybe \"one\" here".

What would be then string with quotes if cursor is at second ✗ on
first line or first, or in the second line?

Should program count all quotes, and what about others? It is
hard to find general boundaries.

It would be easier to find boundaries in a sexp like
'(Something "String \"more\" here").

For that I have tried with:

#+BEGIN_SRC shell-script
  Something
#+END_SRC

And I do not see how it helps with quoting, maybe I
misunderstood. What I could see is that it is making new buffer
and edits it maybe with a different mode.

Do you mean to temporarily, during editing, change the mode and
then come back to original mode?
