My main source was this:

I found the %n %b from the xdvi options when running sources special.
It seems that %n is the line of the cursor in the buffer and %b is the
source file (.tex) which is in the buffer.

In general, if file.pdf was made using synctex, doing "okular
file.pdf#src:100file.tex" should open okular with the content from the
100-th line of file.tex appearing at the center of the screen.

But does it work for you?  I did not work for me.  Anyway, I found how
to keep a single version of okular running:

;; New method introduced in AUCTeX 11.86:
(setq TeX-view-program-list '(("Okular" "okular --unique %o#src:%n%b")))
(setq TeX-view-program-selection '((output-pdf "Okular")))

The "--unique" does the trick!  (Found in the same source.)

But, for some reasons sometimes it does not go to the correct place.
(Most of the times it does, though.)

I found out you can also revert to the old "source-specials" method
(to make it work again with xdvi) by changing
TeX-source-correlate-method variable from "auto" to
"sources-special".  (I did it via the menu entry: latex -> Customize
AucTeX -> TeX command -> TeX view -> TeX source correlate mode.)

I hope this helps.  I could not live without forward/inverse search.

Thanks for your help,
