This is the list of links appearing immediately after the <h1>.
They are contained within an unordered list like so:
<ul> <li class="location home-top-link"><a href="/">Home</a></li> <li class="checkout-top-link"><a href="/checkout.html">Checkout</a> .... </ul>
The key things to notice are the .location class and the .xxx-top-link class.
.location is written out when a link's url matches the current location on the website. See the basics location section for styling tips.
.xxx-top-link is /always/ written out on link list <li>s. It is formed from the link name (in lowercase with spaces and non-word characters replaced by hyphens) with -top-link appended to the end. This is useful for adding background images such as icons. See the basics links section for CSS examples.
