Selected/Restricted Autosubmit with Better Exposed Filters in Drupal
The documentation in CTools suggests adding the class ctools-auto-submit-exclude in the element #attributes key for the form element you don't want to processed: 

function MODULE_search_submission_form_alter(&amp;$form, &amp;$form_state, $form_id) {    
  if ($form_id == "views_exposed_form") {
    if (isset($form['keys'])) {
      $form['keys']['#attributes']['class'][] = 'ctools-auto-submit-exclude';
    }
  }
}
