A nested list is a numbered or bulleted list with subordinate (usually indented) numbered or bulleted lists. Rather than just a list of numbered items (1,2,3...), a nested list may have item 1, then indented items numbered a,b,c or i,ii,iii or some other numbering method before the main number 2. With numbering styles you can achieve any combination of numbering formats you want.
Double-click on a master page to select it. Choose the Text tool from the Tools panel and click and drag on a master page to create a text frame. Choose Type > Insert Special Character > Markers > Current Page Number. Format this character with whatever font family and size you want to use, and then position it on the master page. The character displays as the same letter that the master page is named, but on the individual pages the text displays as the page numbers.
Publisher 2010 includes various typography commands that are designed to help you embellish your text.

Still, if you're using these fonts the typography commands can enhance the appearance of your text.
