Sending Windows Keys in Vugen

Hi All,
I am having an issue with downloading a file from website through Vugen. As Loadrunner does not record the client side activities ie)clicking the save button in the SaveAs dialog, I would like to find an alternate solution for that by clicking the co-ordinates of the save button through "Windows Sendkeys" method.
Anyone has any idea about using windows key in Vugen.
Replies are highly appreciated.
