changing the contents under applications:///

["Mark Farnell" <farnell_mark hotmail com>]

I am running RHL 8.0 with Gnome 2.2 (?).  Last time, some members from this
list suggested that launchers or folders in the menu can be accessed and
changed by going to applications:///   Then I successfully accessed the menu
items under applications:/// by Nautilus.  However, I was unable to add
directories for the menu (when I tried, Nautilus said "unsopported
functions".  Also, when I tried to add launchers under applications, the new
launchers failed to appear after I finished making it (clicking OK) and they
still do not appear after I rebooted the machine.

How can I modify the contents under applications:///        ?
