====================

i don't recall PGP(tm) having the option of "are you sure" for an unsigned 
key, but i didn't spend much time with it. i was left with the impression 
that the key couldn't be used unless it had a signature.

=====================

one can also use edit-key and assign ultimate trust to a key, which will 
make it trusted without a signature.
