Keyboard filtering the list doesn't work with number pad

[willberger]

For example if you press "1" on the num pad String.fromCharCode(e.which) will return "a"

[willberger]

Possible fix (works but probably needs more testing):

var parsedChar = String.fromCharCode(e.which);
if (e.which > 95 && e.which < 106) {
parsedChar = (e.which - 96).toString();
}
// Append the data-filter with typed character
$sod.data("filter", $sod.data("filter") + parsedChar);
