Drupal 7 entityreference autocomplete: Improve the ENTER keydown behaviour (select first on enter)

I created this issue and snippet as better entityreference.module autocomplete widget usability solution in: ‎

Drupal 7 set JavaScript / jQuery trigger on autocomplete field option

With this little snippet you can easily set a trigger on autocomplete field options (suggestions) click:

  1. $(document).on('click', 'div.reference-autocomplete', function(e) {
  2.   // Do what you need to do ;)
  3. });

It's not that easy because the selection click does not trigger any change event on the parent input.
