title: How to use Emacs auto-complete/snippets?
body: <p>I've been using the <a href="https://github.com/overtone/emacs-live" rel="nofollow">emacs-live</a> and it is amazing!</p>
  
  <p>I just can't figure out how to use the autocomplete/snippets, the suggestions pop up, you can cycle through the options, but how do you select an option. </p>
  
  <p>I've tried numinous things to get it to apply the selection, nothing seems to work, it's driving me crazy.</p>
  
  <p>Can someone please help me?</p>
