In org mode there is a way to create a link that will search for text in file./ For example:
[[./functions.pl::sub validate][sub validate]]
This will search for text "sub validate" in file "functions.pl". Unfortunately, there is another function in this file before "validate": sub validate_row.
And the search jumps to it. Can I set the regexp for "sub validate" so it jumped exactly to "validate"?
