If you want to navigate Prev/Next anchor with your Chrome between different anchors in the same page of Confluence, there is a trick to do that with a Javacript Macro in the Confluence Page.
Insert into the page this piece of code, that’s all!
<script> window.onhashchange = function () { if (window.innerDocClick) { //Your own in-page mechanism triggered the hash change } else { //Browser back or forward button was pressed window.location.href = window.location.href } }; </script>
