How to trace where Magento is calling templates from?

Question

I'm working with Magento. See the following code:

<?php echo $this->getChildHtml('topMenu') ?>

Is there an easy way to find where HTML resides. I.e. is there some kind of trace I can use?

Answer 1

In the admin go to System > Configuration > Developer, pick a store from the "Configuration Scope" select in the top left corner, then there will be a new option in "Debug" section called "Template Path Hints". Turn this on and refresh your store page again.

This and more is explained in the Designer's Guide to Magento.
