previous_post_link() and next_post_link().
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: previous_post_smart() and next_post_smart().
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.

previous_post_link( with previous_post_smart(
and
next_post_link( with next_post_smart(
Referrer link
If you also want to display a link back to the list of posts, add this line (also in single.php):
<?php referrer_link(); ?>
Posts with multiple categories
If you want for example to higlight the category that the user came from, you can use get_referrer_category() to retrieve the category object.
For further reference, all the template tags are located in smarter-navigation/template-tags.php.Make sure your host is running PHP 5. Add this line to wp-config.php to check:
var_dump(PHP_VERSION);
