            if (target.hasClass("form-builder-field-node")) {
                if ((keyCode === 27) ||
                    (keyCode === 13 && !target.hasClass("field-textarea")) ||
                    (target.hasClass("field-textarea") && keyCode === 13 && event.ctrlKey === true)) {

                    target.ancestor(".form-builder-field").focus();
                }

                // if ((keyCode === 13 && !target.hasClass("field-textarea"))) {
                //     target.ancestor(".form-builder-field").focus();
                // }

                // if ((target.hasClass("field-textarea") && keyCode === 13 && event.ctrlKey === true)) {
                //     target.ancestor(".form-builder-field").focus();
                // }
            }

nate tells me that .hasClass is not a cheap call.

Mike and I did something like this in aui-datepicker:

var nodeType = node.get('nodeType');

var text = (((tagName === 'input' && type === 'text') ||(tagName === 'textarea')) && node.compareTo(document.activeElement));
