      Notepad Feature: At times when using the GCR Editor, you may want
      to save a header, look at another one, and later retrieve the
      original header without re-reading it. Our GCR Editor features a
      scratch pad (called the Notepad) that lets you save one header in
      memory. You can also edit the notepad header.
