Reply To: How to rtl (right-to-left) a finished book

You can manually do this (certainly not with the single click you were hoping for) but a standard InDesign is not designed to work comfortably with Arabic and other RTL scripts.

For anything more than a single paragraph in RTL scripts (up to and including your 'complete book'), you are far better off with purchasing InDesign ME, a separate version — not an upgrade! — that is targeted specifically at the RTL market.
