This command allows you to add additional pages to your publication. You will be prompted to specify the number of pages to add, and whether to insert them before or after the current page or at the end of the publication.
You also have an opportunity here to specify a title for the new page. If multiple pages are being added, new page titles will be based upon the name you specify. For example, if you specify “Sample” as the new title, pages added will be named “Sample 1”, “Sample 2”, etc.
