free stenography engine and typing tool

 Plover is a small, slick Python application that runs in the
 background and acts as a translator to read steno movements and
 emulate keystrokes in a way that the programs you are using can't
 even tell you're using steno.
 .
 Plover is used today by hundreds of people, ranging from professional
 stenographers, transcriptionists, programmers, and hobbyists. It
 supports:
 .
  - Regular keyboards and real steno machines
  - Media key support to control media, change volume, etc.
  - Comes with a well-developed theory extended from StenEd,
    but with over 50,000 new strokes.
  - Supports JSON and RTF/CRE dictionaries
  - Includes training tools to help you learn
