3.4. Removing Menu Items for All Users

To remove the Dasher menu item from the Accessories submenu, edit /etc/xdg/menus/applications.menu, by adding the following before the final </Menu> tag in the file:

 ...

  <Menu>
    <Name>Accessories</Name>
    <Exclude>
      <Filename>gnome-dasher.desktop</Filename>
    </Exclude>
  </Menu>

</Menu> <!-- End Applications -->

As mentioned above, the appropriate *.desktop file name to use for a given menu item can be determined from the files located in the /usr/share/applications/ directory.
