One of the easiest ways to begin applying numbers is by starting to type a numbered list. Word recognizes that you are creating a list and responds accordingly by converting text that you type into numbered items. The number scheme, delimiter characters that mark the beginning or end of a unit of data and formatting are all based on what you have typed.
Changing the numbering display affects how pages are indicated in the InDesign document, as in the Pages panel and in the page box at the bottom of a document window. The numbering display also affects how you specify page ranges when printing and exporting the document. However, the numbering display does not change the appearance of page numbers on document pages. numbering in indesign
