Yes, org marches down the link handlers and takes the first positive response as the answer. You can make the function arbitrarily complicated of course, if you don't like the behavior, but in any case, it will have to say "yes" (and provide the link in some format) or "no" - in the latter case, org will continue on with the rest of the functions in the list (and fall back to its default if *no* function says "yes"). > Ideally, it would > be great if in the normal stored org link, line number could be > included in the link and would be ripped off from the text to search > the linked file. >=20 I'm confused - what exactly are you asking for here? If you don't use the line number for searching, why would you want to store it?
