Making F1 do something useful in Visual Studio

I tried to run this the first time without any documents open and it threw an error, so I made a small mod to the original code to prevent VS from whining at me under those, probably limited, circumstances:

Dim url As String = "www.google.com/search?q=MSDN"
If DTE.ActiveDocument IsNot Nothing Then
    Dim searchFor As TextSelection = DTE.ActiveDocument.Selection()
    If searchFor.Text <> "" Then
        url = "www.google.com/search?q=MSDN+" + searchFor.Text
    Else
        url = "www.google.com/search?q=MSDN"
    End If
End If
DTE.ExecuteCommand("View.URL", url)

I also like the idea of having it open in my browser rather than a new window in VS.
