A List Style stores the information about how to number each level. That includes the format of the number ( "1" or "a" or "i"), whether the number is preceded by text (eg "Chapter 1" or "Part A"), whether the number includes previous levels' numbers (eg paragraph 1.4.3), and the indents (the distance from margin to number and from number to text).

In the Adobe InDesign document I’m working on here we actually have two master pages, an ‘A’ master and a ‘B’ master so I’m going to select both the left and right hand page frames with the special character in on my ‘A’ master and go to Edit>Copy. I’m then going to double click on my ‘B’ master page and go to Edit>Paste in place. this will then copy the special character and position it in exactly the same place as it appears on my ‘A’ master. numbering in publisher
