Making F1 do something useful in Visual Studio

For Visual Studio 2008 and Visual Studio 2010:
 
1) Open VS, and on the Menu bar select "Tools...Macros...New Macro Project"
2) Call the project "GoogleSearchMSDN"
3) I'm so sorry about this, but VB is involved here. Not my fault, honest!
4) Rename the default Module1 to "DoGoogleSearchMSDN" - right click on the module name in the left hand pan, select "Rename"
5) Enter the following code as the module body:

    Sub GoogleSearchMSDN()
        Dim url As String
        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
        DTE.ExecuteCommand("View.URL", url)
    End Sub

6) Build and save your module.
7) Use the menu bar again: "Tools...Options...Environment...Keyboard"
8) In the "Show commands containing:" textbox, type "Google" - you should see your new macro.
9) Go to the "Press shortcut keys" box, and press F1
10) Press OK.
 
F1 now searches for "MSDN" plus whatever you highlighted.
 
[edit]Took out the "C#" reference in the "searches for" comment at the end - mine does, because I put that in the URL... :-O -- OriginalGriff [/edit]
