Ok, para mí eso funciona con esto ...
var e2key = function(e) {
if (!e) return '';
var event2key = {
'96':'0', '97':'1', '98':'2', '99':'3', '100':'4', '101':'5', '102':'6', '103':'7', '104':'8', '105':'9', // Chiffres clavier num

'65':'a', '66':'b', '67':'c', '68':'d', '69':'e', '70':'f', '71':'g', '72':'h', '73':'i', '74':'j', '75':'k', '76':'l', '77':'m', '78':'n', '79':'o', '80':'p', '81':'q', '82':'r', '83':'s', '84':'t', '85':'u', '86':'v', '87':'w', '88':'x', '89':'y', '90':'z', // Alphabet

};
return event2key[(e.which || e.keyCode)];
};
var page5Key = function(e, customKey) {
if (e) e.preventDefault();
switch(e2key(customKey || e)) {
case 'left': /*...*/ break;
case 'right': /*...*/ break;
}
};
$(document).bind('keyup', page5Key);
$(document).trigger('keyup', [{preventDefault:function(){},keyCode:37}]);
