One of the primary ways to navigate PeopleSoft is to use the Homepage. 

The Homepage is best described as a tile menu. As you select menu items, sub-menus dynamically display on the left-hand side navigation. Sub-menus often contain sub-menus of their own. The menu items displayed on Homepages are different per user. The content of your menu depends upon your level of security. Your menu will provide navigation to each of the pages you have permission to work with. The greater your level of security, the more populated your tile menu.

If you click on a tile anywhere on the Homepage, a list of components (collection of folders and pages) will be displayed.
