[OS X TeX] [External] double page view

[Richard Koch]

Zbigniew,

Let us do this slowly. In Preferences under the Preview tab, there is an item giving the choice

	Pages Flow Left to Right
	Pages Flow Right to Left

The first of these is the correct choice for almost all languages, since we write from left to right. The main exceptions are authors using Hebrew, Arabic or Persian because they write right to left. So select Pages Flow Left to Right.

-----------------------

The next choice is the important one for you The name of this choice is "DisplayAsBook" and the value can be YES or NO. The default is YES, which gives one single page at the top, and then pairs of pages afterward. The other choice is NO, which gives double pages all the way down. 

Before selecting a choice, you can test which one you want. At the top of one of your documents, write one of the two magic lines

% !TEX bookDisplay
% !TEX standard Display

Try this. If you use the first one, you'll get one page on top and then double pages. If you use the second one, you will get double pages all the way down.

Usually people want the top one because books are designed so there are an odd number of preliminary pages until the main text starts. So if you start with a single isolated page, then when you come to the main material in the book, the pairs of pages will agree with the pairs you see when you open the book.

But if for some strange reason this is not what you want, and only then, you can change the default without using these magic lines. I seriously doubt that you'll want to do that after you try these experiments, so I'll omit describing the Terminal actions unless you request them.
