We're familiar with regedit.exe in windows operation system but we didn't know ( as a newbie ) that GNOME got their own configuration tools. I'm using LinuxMint right now but it should works for all GNOME on all unix/linux OS..
open up your terminal then type in this command
#gconf-editor
then enter ... hahaha.. stupid thing for expert but a new knowledge for a newbie like me..
