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 (server-start) (require 'okular-search) (add-hook 'LaTeX-mode-hook (lambda () (local-set-key "\C-x\C-j" 'okular-jump-to-line))) (add-hook 'tex-mode-hook (lambda () (local-set-key "\C-x\C-j" 'okular-jump-to-line))) See both the okular-search.el file as well as the lines above. Your help is greatly appreciated. Thanks a lot.
