Clicking on the "Search Pages" in the "Page Manager" submenu wil bring you to a page where you can view your existing web pages.

Clicking on the box beside the Page title (About, Contact, Home, etc.) will make that page display on your website.  Alternatively, you can click the box beside URL to include every page.

Clicking the “Edit” link will allow you to edit the page.  This is also the same page accessed when you click on the “add pages” link in the page manager submenu.
