title: Correct way to detach from a container without stopping it
body: <p>In Docker 1.1.2 (latest), what's the correct way to detach from a container without stopping it?</p>
  
  <p>So for example, if I try:</p>
  
  <ul>
  <li><code>docker run -i -t foo /bin/bash</code> or</li>
  <li><code>docker attach foo</code> (for already running container)</li>
  </ul>
  
  <p>both of which get me to a terminal in the container, how do I exit the container's terminal without stopping it?</p>
  
  <p><code>exit</code> and <code>CTR+C</code> both stop the container.</p>
