How to know which layout a product is using?

[OneMore]

Hi,

I am using the default theme and template.

In the list of layouts, I had a custom layout for one product "Product: My product title".
This was likely of an accidental duplicate of "Default product page" when I was experimenting with layouts.
In "Design > Layouts", I could delete the custom layout, and it seems that the product reverted back to using the default product layout.

However, I still have this question: how do I see which layout a product is using?
Apart the product name being listed in the layouts drop list (in "Design > Layout") I cannot see the information about the layout being used in the product page (Layout tab).

Thank you.
