Click next to continue – WordPress CMS

I’m using WordPress as a CMS and wondered if anyone had any idea on how to implement a ‘click next to continue’ scenario, but not reading posts/articles but just reading page content.

I kind of cheated but on clicking next the navbar link that should be highlighted loses it’s focus (bold type) as I am going to a new page instead of making use of the elements on the current page.

Or is there a plugin with this function?

Any help/advice would be much appreciated!

Thanks. :o)
