Browser 'Back' button - can it be monitored as well?

Hi, this is a great little module - anything that will make someone switching from a regular 'word processing' background feel more at ease is great. Of course, a web browser is not the same as a word processor...
Knowing nothing about how browsers work, I was wondering - is it possible to monitor clicking on the browser 'Back' or 'Forward' button as well? This module gives a warning when you click on a link - but a lot of times people simply navigate away using the 'Back' button. Thanks for this great module!
