                    var idx = inputs.index(this);
                    if (idx == inputs.length - 1) {
                        inputs[0].select()
                    } else {
                        if (inputs[idx + 1].readOnly == true) {
                            inputs[idx + 2].focus(); // handles submit buttons
                            inputs[idx + 2].select();
