Because this document has facing pages, we want to insert page numbers on both the left and right pages. For now, navigate to the bottom-right corner of the right-hand page by zooming in (Ctrl + [Windows] or Cmd + [Mac]). Select the Type Tool (T) from the Tools Panel (Window > Tools) and drag to create a small text frame, resting the top of the frame against the margin.
Note  If TAB and SHIFT+TAB do not work for changing the indents for outline numbering, you probably have the option Tabs and Backspace set left Indent turned off. To change this setting, from the Tools menu, choose Options. Select the Edit tab and check the option Tabs and backspace set left indent. As an alternative to turning this option on, you can instead use ALT+SHIFT+LEFT ARROW or RIGHT ARROW to increase or decrease outline numbering. numbering using publisher
