Re: Setup document for Right Hand Binding in UK English CS6.

Procedure for JavaScript fix.

1. Copy the following code:
   app.documents[0].documentPreferences.pageBinding = app.documents[0].documentPreferences.pageBinding == PageBindingOptions.LEFT_TO_RIGHT ? PageBindingOptions.RIGHT_TO_LEFT : PageBindingOptions.LEFT_TO_RIGHT;
2. Open 'ExtendScript Toolkit' application or program.
   Supplied with Creative Suite. (For Mac it's in : Applications > Utilities > Adobe Utilities - CSxx > ExtendScript Toolkit CSxx
3. Select 'New JavaScript' from the File menu in ExtendScript Toolkit.
4. Paste the code in. (copied from point 1).
5. Save as <filename>.jsx (eg. ChangeBinding.jsx) to desktop or documents folder.
6. Copy from saved location into : Applications > Adobe InDesign CSxx > Scripts > Scripts Panel > Samples > JavaScript. (Mac)
7. Start InDesign > Open document > Open Scripts Window > Double click on ChangeBinding.jsx script to run on open document.

NB. Will work in either direction. Left hand bind to the Right hand bind. Right hand bind to Left hand bind.
