I'm afraid i don't understand what you're saying. Is it that if i want
to use keys i can not use document()?

Good question, i really don't know. Probably at the beggining i had
two diferent doc's and use it, and many copy&pasts after it
survived...

But it's not needed, you're right, i've got then out.

Can you elaborate on the keys usage?
