Forward and reverse synchronization between the TeX source and the PDF output using SyncTeX is an immensely useful tool when writing larger documents. Sometimes, especially when the synchronization is not working as expected, I would like to see the synchronization anchors in the PDF file. I know that the information is stored in .synctex.gz
file in some form, but this is hardly transparent for a human reader. Some graphical indication over the PDF output would be great. Does this exist?
I am working on Windows. Solutions for other systems are of course welcome, though they won't help me.
