title: Is this a built in drawable?
body: <p>In <a href="http://snpent.com/images/button.gif" rel="nofollow noreferrer">this linked image</a> , I see the button on the right quite often in a lot of apps. On my Moto Droid, it is used extensively in the settings app. It is also used as the default AlertDialog icon. Can I use this via a android.r.drawable?</p>
