In Vanilla Gnome there is an "Accessibility" menu item, but there isn't one in Fedora's Gnome and the tools are not shown in any of the other menus.
I don't think the accessibility tools need their own toplevel menu, but they should be in the menu somewhere.
Which tools? The only things that should be in the menu are "Accessibility" and "Assistive Technology Support". gok and gnopernicus do not get a menu item as they really can't be launched outside of gnome-session, and are turned on in the "Assistive Technology Support" capplet.
