 *  - Names of printable alpha-numeric characters are used (e.g. "A", "R",
 *    "3", etc).
 *  - For non-alphanumeric characters, Unicode:ish names are used (e.g.

 *    correspond to the Unicode standard (usually for brevity).
 *  - Keys that lack a clear US mapping are named "WORLD_x".
 *  - For non-printable keys, custom names are used (e.g. "F4",
