I am looking to track down the file (and it's location) that generates the "Proceed to Checkout" button in the Magento cart.
Try adding a product to the cart, and then proceeding to the cart. The "Proceed to Checkout" button is on the right hand side of the cart.
I am using a hacked-about variation of the blank theme, if that makes any difference.
Thanks in advance for your help.
The code that produces the Proceed to Checkout link is in templates/checkout/onepage/link.phtml
By default the block for it is in checkout.xml;
