In the preceding screenshot, the user has logged in as the Administrator and entered the Trends in Tourism course. Note the breadcrumbs trail (the Navbar) in the top-left corner of the screen, which tells us the name of the site and the short name of the course.
At the upper-right side of the screen, we see a confirmation that the user has logged in. That is not a part of the Navbar, but it usually appears next to it. There is also a box that allows you to turn on editing.
