How Do I ... Copy a page?
This feature is a bit hidden and unintuitive within the AEM Ensemble interface. You have to view your site in Column View in order for the Copy command to appear in the menu above the file list. The copy command does allow you to copy multiple pages at a time, unlike the Move command used to move and rename pages. It will also copy recursively, meaning that any sub-pages under the page(s) being copied will also be copied.
