Magento Verification Method List

Question

Is there a way to see the list of methods that is called in the shopping cart view.

<ul class="checkout-types"> <?php foreach ($this->getMethods('methods') as $method): ?> <?php if ($methodHtml = $this->getMethodHtml($method)): ?> <li><?php echo $methodHtml; ?></li> <?php endif; ?> <?php endforeach; ?> </ul> 

This code is in the views wherever the Go To Checkout button appears, but my Paypal Express button is not listed. I can track it down to the paragraph of the block, but then the code loses me (that is, what calls setChild to make the "methods" a child and give it a block?).
