"Actions" Menu: Can anyone tell me where the XML files are located?

[WP Hewitt <wphewitt comcast net>]

Hi
   I would like to modify the "Actions" menu on the Gnome Panel...... I 
want to move some things around.....
But, I serached the whole filesystem and cannot find the config files 
for it.... I know where "Applications" is and can mod it, but I would 
like to modify the "Actions" menu.....

   I looked at freedesktop, wrote the list there and searched 
Google..... Cant seem to find any info anywhere....

I am interested in editing the files, nothing from a GUI.....


Any hints, advice etc..... would be appreciated......

OTOH, perhaps this is a secret?

TIA
