   ' Check to see if UndoContext object is already open.
   If DTE.UndoContext.IsOpen = True Then

   Else
      ' Open the UndoContext object to track changes.
      DTE.UndoContext.Open("RemoveNewLines", False)
   End If
   MsgBox("Current IsAborted value: " & DTE.UndoContext.IsAborted)

   ' Perform search for newline characters and remove them.
   If strTS <> "" Then
      txtSel.Delete()
      strTS = Replace(strTS, vbNewLine, "", Compare:=vbTextCompare)
      txtSel.Insert(strTS)
   End If

   ' Check to see if you want to discard changes.
