The Course Navigation helps you get to where you want to go within your Canvas course [2].
The Breadcrumb Navigation shows you where you have navigated to inside of a course and gives you a quick and easy way to move backward [3].
The Sidebar will be mostly empty for Observers [4].
The Help link is very important. Click the Help link when you need assistance. [5].

The Course Navigation links on the left side of your screen help you get to where you want to go inside of Canvas.
