Display ID/Sku in checkout-stepX

[icutillas]

Hi everyone,

I'd like to know whether it's possible to display the ID/SKU in the checkout page.

I have been testing many variables (such as [itemid], [ITEM_ID], etc) and blocks (product, itemoptions, SHOPPING_CART_ITEM, etc...), but it does not work or doesn't show what I want.

If anyone can give me a hand... I really appreciate it!

Regards,
Ivan
