5. Insert the code to paste a new GUID into the current cursor position / selection:
   
Public Sub PasteNewGuid()
DTE.ActiveDocument.Selection.Text = "{" & System.Guid.NewGuid().ToString("D").ToUpper() & "}"
End Sub
6. Save the macro project and close the Macro IDE
7. In Visual Studio: Tools > Options, select Environment > Keyboard

9. Select the command in the list
10. Ensure Use new shortcut in: has Global selected
