Adding open-with items to context menu

[Bill Moseley <moseley hank org>]

Not sure if this is GNOME issue or more specific to the WM, but can
someone point me to info on how the context (right click) menus work 
for icons on the desktop?  How do I add or modify items and the
command lines used.

Thanks,
