It’s a lot easier for me to hit ctrl-f than the right arrow key. Especially since I use my caps-lock as a ctrl key. These are Emacs navigation key combinations, and I can’t really work without them. TextMate has them built-in which is wonderful, Gedit on the other hand does not.
However, you can dig into your gconf settings and specify a “gtk key theme” other than the default one. You can specify emacs! Doing so, will allow you to use key combo’s like ctrl-f in Gedit and other Gtk applications.
Set the value of:
/desktop/gnome/interface/gtk_key_theme
To:
Emacs
