The default chordset of the SpiffChorder is based on one developed jointly by the United States National Aeronautics and Space Administration and a commercial input device manufacturer in the late 1980s, referred to as the "modified NASA" chordset in the SpiffChorder source code and documentation. Since I spend most of my time in a text terminal, I put together a chord chart for the SpiffChorder which fits safely into a standard 80x24 character screen (I made it 78x22 to allow for a one-character border on all sides). I also left four empty entries to accommodate custom macros.
