Populate text boxes with values from other text boxes?

How do I populate text fields with values from other text fields?
For instance, shipping and billing info. I'd like to create a check box that automatically fills the text box fields under billing with the same values as their corresponding text box fields in shipping. I'm sure it's doable, I just don't have any programming chops, so I have no idea where to start.

Thanks in advance for the help,
Zach
