If you mean to unset a key of an app, lets say e.g. gedit, it can be achieved either via GUI or via CLI using gconftool:
gconftool --recursive-unset /apps/gedit-2

##see also manpage
man gconftool
http://library.gnome.org/users/gconf-editor/2.22/getting-started.html.en

config files of each app are as .xml in
/home/username/.gconf/apps
##the dot in front means hidden folder, to unhide folders in Nautilus: ctrl+H

btw. we had once a discussion in bug section of lp about gconf-editor not deleting app entries.
The answer was gconf-editor isn't responsible if an app, after it was removed from the system, still remains in gconf-editor. Then it's a misconception of the app not of gconf-editor.

Acutally there are no 'tricks', every highlighted key shows an explanation in a sub-frame.
Except of a short youtube video (keyword ubuntu tutorials), the (gnome) link already mentioned and gconftool, you may observe what users provide and learning by doing, presume you know what you're doing.

Small examples below can also be achieved via GUI.

Howto make Gedit showing more 'recently used' entries:
gconftool-2 --set --type=int /apps/gedit-2/preferences/ui/recents/max_recents 10

Howto check if Firefox is the prefered browser:
gconftool --get /desktop/gnome/url-handlers/http/command
if it isn't:
gconftool --set /desktop/gnome/url-handlers/http/command "firefox %s"
