How put a product display on the "Shop" not the "Home" page? I have created all suggested types and objects for a product display (drupal commerce module) but it only shows on the "Home" page (which I have renamed "News"). I have a page named "Shop" for this purpose i.e. where I want the products to be on. How do I tell drupal to place the product display there?

(In fact, how does one edit the content of a page in general?)

Thanks a lot.
If I understand you correctly, you want to tell Drupal to use a different node for the home page.   If this is what you mean you can do this by going to  

Home -> Administer -> Site Configuration 

You can change the node for the Default front page there.
