A little-known feature in Apple’s Pages is a “Two Up” page view. The “Two Up” view allows you to see two pages of a document next to each other vertically, so the document appears more like a book. If you are working on a large monitor with smaller-than-normal pages, this feature could be quite useful and increase your productivity.
To switch between the “One Up” (the default) and “Two Up” page views, click on the tiny box at the bottom left of any pages window where the percent-size of the page you are viewing is shown. A small pop-up menu will then allow you to select whether you want “One Up” or “Two Up” view.
From that same menu, you can select “Fit Width” which will resize the pages so they can fit perfectly in your Pages window. This feature works with “One Up” view as well, of course.
