Looking at the Editor in Page View
To make the Editor appear more like a printed page, including document edges and margins, choose View⇒Page View⇒Show Page View.
Want to see two pages side by side? After you turn on Page view, choose View⇒Page View⇒Two Pages Across.
Just remember, Page view isn’t necessarily an accurate representation of how pages will print; it’s merely a visual preference. The final layout of your output depends on your compile settings (see Part IV for details on compiling).
To turn off Page view, choose View⇒Page View⇒Hide Page View.
