I found this nice demonstration showing the use of SyncTeX with Gedit and evince. I would like to use this nice feature but my Ubuntu Natty Narwhal (11.04) does not have Gedit in the version of 2.32.
kon@pc:~$ gedit --version
gedit - Version 2.30.4
kon@pc:~$ evince --version
GNOME Document Viewer 2.32.0
How do I update Gedit being able to use SyncTeX?
