When asking my question about creating a unified forward-inverse-search tag, I missed the fact that there is also a synctex tag. SyncTeX is a special technology for forward-inverse-searching, but I think it is appropriate to use the general tag for it. Therefore I suggest to make synctex a synonym of forward-inverse-search and to merge the existing questions.
EDIT: As my proposal got some, but not too many upvotes, let my elaborate: I think that even if there were other techniques for forward-inverse-searching in (La)TeX than SyncTeX, the current synctex tag and the more general forward-inverse-search are closely aligned, and the small number of overall questions does not warrant specialized tags (neither for SyncTeX nor for other techniques).
