I'll show you a quick way to tidy up the Navigator pane. The rightmost button of the Navigator toolbar is a set of four arrows pointing inward. If you roll your mouse over the button, the tool tip will come up saying "Collapse All". As the tip implies, this button will collapse all of your expanded folders and projects.
q 5.1(a) Click the Collapse All button on the Navigator toolbar.
Okay, now that the projects are closed, I'd like you to close the documents you had open as well. This is done by rolling your cursor over the tab for each document in the editor pane and then clicking on the X that appears.
q 5.1(b) Close the Step List.txt resource.
q 5.1(c) Close the .project resource.
