Checkout Questions

I need to ask a few more questions and then I won't need to bother you for a while:
1)My client wants to be able to add a product to the shopping cart but stay on the same product listing screen and not have it go to the cart screen. How can we arrange this?
2)On the first shopping cart screen, how can we insert a link that says
"Continue shopping"?

1. You can change the option "After a product is added to the cart" to "Always stay on the same page" in the checkout tab of the configuration.

2. In the same screen, you need to fill the option "Continue shopping button's URL".

It all works great now Nicolas...thank you so much!
