/**
 * Keyboard handling is a mess. http://unixpapa.com/js/key.html
 * It would be good to use DOM L3 Keyboard events,
 * http://www.w3.org/TR/2010/WD-DOM-Level-3-Events-20100907/#events-keyboardevents
 * however only Webkit supports them, and there isn't a shim on Modernizr:
 * https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-browser-Polyfills
 * and when the code that uses this KeyEvent was written, nothing was clear,
 * so instead, we're using this unmodern shim:
 * http://stackoverflow.com/questions/5681146/chrome-10-keyevent-or-something-similar-to-firefoxs-keyevent
 * See BUG 664991: keyboard handling should be updated to use DOM-L3
 * https://bugzilla.mozilla.org/show_bug.cgi?id=664991
