Section 4.2: Single-Page Mode
Single-Page Mode allows you to read your documents one page at a time, instead of the default "continuous scrolling" display. Also, because it only needs to display one page at a time, this mode allows for higher display resolution and crisp content at very high zoom levels. Because of this, Single-Page Mode is particularly useful for viewing very large single-page documents, such as maps.
Single-Page Mode adds translucent "Next Page" and "Previous Page" buttons to the PDF display interface:

Single-Page Mode navigation controls
Use these controls to advance between nearby pages in your document. Of course, you can also use the use Go to Page feature to quickly navigate to any page in your document.
