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.
