How can I run command like gconf-editor?

How can I run command like gconf-editor?

(I installed 'files and folders' plugin. )

for example. After install gconf-editor. This program

action in terminal
------------------------------------------------------------
~$ gconf<tab><tab>
gconf-editor gconf-schemas gconftool
gconf-merge-tree gconfsharp2-schemagen gconftool-2
~$ gconf-<tab><tab>
gconf-editor gconf-merge-tree gconf-schemas
~$ gconf-e<tab>
~$ gconf-editor
-----------------------------------------------------------------

Also, in 'Gnome Do' shell, I can run with full typeing 'gconf-editor'.
But I want to know auto completion method. I try to many other method. I don't find yet.

Can I do it?
