title: What exactly is the HTML5 <command> tag and what is the browser support
body: <p>I've read the <a href="http://dev.w3.org/html5/spec/Overview.html#the-command" rel="noreferrer">HTML5 spec for <code>&lt;command&gt;</code></a> and found the information on this element very vague.</p>
  
  <p><a href="http://www.jsfiddle.net/StZM3/3/" rel="noreferrer">I've tried it out</a> and found that it is <strong>not</strong> working in Chrome (latest version) and it <strong>is</strong> working on Safari (even older ones), sorry no FF (don't shoot me please) - Mac only test.</p>
  
  <p>I can't understand what is the use of this element or even if I'm using it correctly.</p>
  
  <p>I thank you in advance for any clarification about it!</p>
