title: HTML input attribute "accesskey" browser compatibility
body: <p>What browsers are implementing the input attribute "<code>accesskey</code>"?<br />
  Is the behavior consistent cross browser?<br/>
  Is it safe to use <code>accesskey</code> as just an extra data attribute (like the "<code>rel</code>" and "<code>rev</code>" are sometimes used on the <code>a</code> tag)?</p>
  
  <p>Also, is there a way to capture the "onaccesskeypress" in JavaScript? Does it just fire an onclick event?</p>
