TIL that we can use references and labels in Org babel!
You can also add a ‘-r’ switch which removes the labels from the source code. With the ‘-n’ switch, links to these references are labeled by the line numbers from the code listing. Otherwise links use the labels with no parentheses. Here is an example:
#+BEGIN_SRC emacs-lisp -n -r
(save-excursion (ref:sc)
(goto-char (point-min)) (ref:jump)
#+END_SRC
In line [[(sc)]] we remember the current position. [[(jump)][Line (jump)]]
jumps to point-min.
