Is it possible to grab a link to a region in a file in such a way that
C-c C-o visit the file after narrowing-to-region?
The reason I'd like this is that I'm starting using org-mode for
requirement tracking and when referencing a standard I'd find
preferable to open only the relevant fragment rather than the complete
document.
Regards,
Maurizio

I don't think that's currently possible without writing a little lisp
code. There is an org-follow-link-hook but it doesn't seem to be
executed for all link types - only browser urls if I'm reading the code
correctly.
The following patch seems to fix it so it executes for plain file links
too. You can probably create a function that goes to the point and then
narrows the text around the point using this hook.
I tested this by setting the hook with
(setq org-follow-link-hook 'hide-other)

Subject: [PATCH] Enable org-follow-link-hook for all link types
This hook was only executing for browser links. Now we always execute the hook
after visiting a link assuming no error occurs.

But the region should be encoded in the link, as there no way to figure
out what is the extent of the interesting area automatically.
Regarding org-follow-link-hook, I'm not familiar with org-mode code, but
it seems to me that is invoked for all URL types, but only after the
'viewing' has happened. I may well be wrong.
Thanks for the suggestion.
Regards,
Maurizio

Current links don't have region information - just a match to the first
occurrence of text in the file. What would a region link look like and
how would you generate one?

That didn't seem to be the case for my quick test of the hook.

That was a bug, fixed now.
