* - 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.
* "COMMA", "LEFT_SQUARE_BRACKET", etc). Note that some names do not
* 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",
* "BACKSPACE", etc).
