8106 \"explore\" - start the Windows Explorer on DOCUMENT
8107 \"edit\" - launch an editor and open DOCUMENT for editing; which
8108 editor is launched depends on the association for the
8110 \"find\" - initiate search starting from DOCUMENT which must specify
8112 nil - invoke the default OPERATION, or \"open\" if default is
