There is no such thing as homepage directly. It is made of bunch of modules, so you need to go to extension->modules and find correct one. In most cases they names are self explaining.
With the anchors - you need to know a little bit of HTML. Anchors in menu points to HTML elements that has ID. So with use of FireBug, Web Developer Tools or similar developer tool you need to find in source code place where you would like to scroll too, then search for a element with ID, and finally use it in Lenik as #ID.
If it is over your skills - please share your site URL, point to where you would like to scroll to, and I'll provide you list of anchors.
