Sorry if this has been sent more than once. I was trying to reply from gnus, and it isn't clear that happened. The code block in that example is also missing a closing parenthesis. this post reminded me of this cool feature of source blocks, so I tried it out. The code block itself does not seem to run, even after fixing the closing parenthesis. #+BEGIN_SRC emacs-lisp -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. I get: save-excursion: Symbol's function definition is void: ref:sc unless I put a ; (comment) in front of (ref:sc) and (ref:jump). Then the block runs, but still does not export correctly. When I export this to a pdf file, the ref: is removed from the references, but (sc) and (jump) remain in the code block, and as Jambunathan noted, the links in the text are not replaced by line numbers. I hope that helps track down the problem! my org-version is 8.2.5g, but I also see the problem with 7.9.3f. Let me know if other information would be helpful. thanks, Thanks.
