From the included readme.txt:

Command line syntax:

Search Google Desktop with the Company name from the current record:
c:\apps\goldmine\GM2GDSearch.exe /field:contact1->company

Search Google Desktop with the Key5 value from the current record:
c:\apps\goldmine\GM2GDSearch.exe /field:contact1->Key5

Search Google Desktop with the Contact name from the current record:
c:\apps\goldmine\GM2GDSearch.exe /field:&contact

Pull the Name and Address block from the current record:

And so on.
