This is a LaTeX package, that adds links to each paragraph. If the links are pressed the text editor will be opened at the correct line number. This eases finding the correct spot in the tex source files.
synctex
In the meantime I have found out that synctex exists, which seems very promising. I have not yet had a chance to upgrade to a new enough software version of evince to check it out though.
Getting it
You can browse the code online, or get it using:
git clone https://git.sipsolutions.net/editlinks.git
Usage
Just use the "draft" mode, and include the package using \usepackage{editlinks}.
