keyHandler:function(e) {
    if(disabled===true) {
        return true;
    }
    if(locked===true || document.activeElement.readOnly===false) {
        return false;
    }

The document.activeElement.readOnly===false function return always false when your active element is a Input, Select or Textarea. If you have a form in the site it does not work with the plugin!

How can I disable the keyHandler for the form?
