Close a menu programmatically

Hi!

I would like to programmatically close a menu. The reason being that I 
have a search field in the menu item (much like the Help menu under 
Leopard). When the user hits enter, I open a new window and thus I 
would like the menu to go away.

I am under the impression that I need to drop back to Carbon. The 
catch being that my Carbon knowledge is close to nil (shall I say 
NULL?).

Or is there a Cocoa way?

Best,
