How to show pages side by side in Apple Pages

Published in Apple
One of those things that is dead easy if you know where to look. To show the pages side by side in Pages (the Apple app). Just open your pages file and click the bottom left corner (where the zoom is) and choose the "2 up" option.
You may also want to know that if you view>show inspector you will be able to turn the option "facing pages" on. 
What the difference between the two is, I'm really not quite sure but I think if you are looking for a solution to how to show pages two up while you work on them you might find one of these is more appropriate than the other.
