steno-display.js

// Display keys for arbitrary steno stroke sequences.

// To use, simply create a new StenoDisplay for your container
// element (can pass element id name or the element itself) and
// then call the set method with the steno or pseudo-steno string
// (strokes separated by slashes).
//
// It needs a bunch of help from styles: see the `#stroke` entries
// in `style.css`.
