click on link to display text

I've seen quite a few tutorials where you'd add/remove test in a div but it was all within the same div. Could you recommend a tutorial or post a simple snippet of code that would illustrate adding removing text by clicking on a link in one div to display text in another div (in a different part of page)

To be more specific, I've got a few product names listed in a sidebar. If I click on any of them, its description will be displayed in the main area of the page.

Thank you
