When displaying a single post, you might want to show links to the previous and next posts in the same category.
That’s fine; WordPress let’s you do this with <code>previous_post_link()</code> and <code>next_post_link()</code>.
But what if that post is in multiple categories?
What if the user came to that post from a tag page or from an author page? Wouldn’t it make more sense to display previous / next posts from that particular set?
Well, you can do this with a similar pair of functions, provided by this plugin: <code>previous_post_smart()</code> and <code>next_post_smart()</code>.
Here’s how it works:
Whenever a visitor goes to an archive page (category, tag, date, author, search etc.), the plugin notes which archive it is in a browser cookie.
Then, if the visitor goes to a single post from that archive page, the plugin generates the prev / next links based on the information in the cookie.

Create next/previous links for pages. Adds the functions next_page_link() and previous_page_link() which links sibling to page(s). 
If your page doesn’t have a direct sibling the plugin will try to go out to the parent of the current page and get the parent’s next sibling. If enabled the plugin will also loop from end->beginning and beginning->end.
This plugin is great for utilizing WordPress for presentations. If you create a set of pages. This plugin will cycle through them. Additionally you could utilize some javascript to create a timer to automatically go from page to page.
This plugin is based on ‘Next and Previous Page not Post’ by Matt McInvale. Although it’s gone through almost a complete rewrite from his release in 09. This plugin is a bit more optimized to take advantage of newer plugin techniques. Includes code from banesto as well regarding references to grandparent pages. Also added in additional features such as $args array for easier customization down the road. This plugin is great for utilizing wordpress as a presentation tool.
