find cell from bubble

given :

       var me = this;
        this.editor.on('open', function (e, type) {
            var edt = me.editor;

            if (type === "bubble") {
                $(document).on('keydown.editor', function (e) {
                       // find current cell
                 });
             }

          });

Is there an easy way to determine which cell the bubble is acting on?
My page has two tables and two editors running.

Thanks,
Scott
