Im using the toggle script demonstrated here:

http://www.sohtanaka.com/web-design/examples/toggle/

It works perfectly, but im wondering if it is possible to have a button to expand all and contract all.

Ive been reading through this page:  http://api.jquery.com/toggle/

Im having a hard time understanding it, because this is one of the first things I have worked on with jquery. Can anyone help explain how I can do this?
