title: Select first suggestion from Typeahead.js when hit Enter key in the field
body: <p>I want to select first available suggestion from Typeahead.js suggestion items, when I hit Enter key while I'm focused on that field.</p>
  
  <p>I got this code by now:</p>
  
  <pre><code>$('#cities-prefetch .typeahead').on('keyup', function(e) {
      if(e.which == 13) {
          var value = $('input:text#city').typeahead('val');
      }
  });
  </code></pre>
  
  <p>But that only fetches the current selected value from with in the field itself.</p>
  
  <p>Please help!</p>
