When using the keyboard to navigate through the help texts I noticed a link that appeared when focus moved from the heading on the page. A link that wasn't visible before suddenly appears. The link always has this text "Go to primary content". When I look at the HTML I see this div element:
<div class="zz-skip-header"><a href="#BEGIN">Go to primary content</a></div>

I'm not sure if this link should be there or not...
