How can I find out what templates are used to render a page?

[briangreul]

When doing minor modifications it's often nice to know what templates are involved. It's also nice to know what templates are used to build a page for debugging purposes.

Is there a way to find out what templates are being used on a given page?

I have a debugging issue right now where I broke something minor and it's killing inline moderation. I've looked at the 3 or 4 templates, but I don't see anything evil. The pages all work fine, it's only when I try to moderate them.

Generating a list of templates to evaluate would help me to narrow my search.

I've also done a lot of trial and error when trying to change something. I hate hunting for the offending template that needs modification.
