What I have tried:

I have tried this but it doesn't work. (line 600 / js). Any idea?? Thanks in advance

 events: {
      'click a': 'onPresetClick',
    'keydown a': 'keyAction'
    },

keyAction: function(e) {
  var code = e.keyCode || e.which;    
    if(code == 13) { 
      var id = $(e.currentTarget).attr('data-preset-id');
      this.$items.removeClass('active');
      $(e.currentTarget).addClass('active');
      dispatcher.trigger(dispatcher.EventKeys.PRESET_SELECTED, presets[id]);
    }
    },
