The anchor text is the page title, and the href is the current location. This is useful for interacting with the current page with extensions, and also changing which chrome profile you are viewing the page with
javascript:!function(a){var b=document.createElement("textarea"),c=document.getSelection();b.textContent=a,document.body.appendChild(b),c.removeAllRanges(),b.select(),document.execCommand("copy"),c.removeAllRanges(),document.body.removeChild(b)}("["+document.title+"]("+document.location+")");
