Moodle uses the so-called breadcrumb trail interface for its navigation; the name is derived from the Hansel and Gretel fairytale! Once you select a menu or sub-menu in the site administration block, Moodle displays the respective crumbs
in your navigation bar. These crumbs can be used to jump back to any previous menus. In the menu shown in the figure, the trail consists of five crumbs (Moodle | Administration | Modules | Activities | Manage activities):
The first crumb is always the name of the site, and represents your Moodle front page. So if you ever get lost, for example, when working on an area in Moodle when the sticky Site Administration block is not shown, click on the first crumb and you will be in a familiar territory.
