KB User's Guide - Documents Tab - Demo - Up, Previous, Next - Page Four
From here click Up to go back to the first page (15335).
Click Previous to go back to the third page (15337).
Since this is the last document in the series the Next field was left blank and therefore the Next label and links do not appear. The Next link could point to the first document in the series or any active document. For the purposes of demonstration it was left blank in this case.
If a user does not have access to a document that is included in an Up, Previous, or Next link, that link will not be displayed for that user.
