What are defualt settings?

I see this as default settings

  $settings += array(
    'autoFit' => TRUE,
    'draggable' => TRUE,
    'width' => 600,
    'height' => 400,
    'automodalClose' => TRUE,
    'automodalReload' => FALSE,
  );

are they also used if i just add ".automodal" to links, or do i have to do some additional settings. As currenly my automodal is not closing. (when creating content)
