Hi, there, That is interesting. Sorry for the confusion, this is the same
issue I have been trying to describe.
Yes, I have configured emacs to forward jump to okular, just like we can do
it with kdvi, here is the okular-search.el file I used for emacs to jump to
okular, actually I modified kdvi-search.el to achieved it. It works fine
except whenever it jump to the right place but auto-center the page, which
is quite annoying.
When we use emacs to jump to kdvi, the page horizontal position doesn't
change, but okular will always auto-center horizontally the new page.
In addition, here is the lisp code I put in .emacs in order for it to do so:
;; start the server so that the inverse search works
(add-hook 'LaTeX-mode-hook (lambda () (local-set-key "\C-x\C-j"
(add-hook 'tex-mode-hook (lambda () (local-set-key "\C-x\C-j"
See both the okular-search.el file as well as the lines above.
Your help is greatly appreciated. Thanks a lot.
