how to animate scroll all the way down to the bottom of the window
<p>I have a list of comments. When a user submits a new comment it is appended to the end of the list. This causes the user to need to scrolldown to see the appended comment.</p>

<p>I want to auto scroll down in an animated way.</p>

<p>How can I animate scroll down to the bottom of the window?</p>

<p>thanks</p>
