apt-key list, I see a key which I wish to remove.

man apt-key tells me that I may delete a key by executing
apt-key del keyid. It also tells me that
finger) will list trusted keys with fingerprints, so I am assuming that
3241 413F 3CE0 B919 E82F DCA0 6239 92CF C9A9 7C2C is the fingerprint and not the keyid. I've messed around with
gpg --list-keys and
gpg --list-public-keys, however, it doesn't list any keys but creates
~/.gnupg/ with various non-text files which do not display the key IDs.
How can I identify the keyid so I may delete the key?
PS. Before asking this question, I searched for a solution, and some recommend not using "short key ids". If I should not be deleting keys by the keyid as described by
man apt-key, please provide the appropriate way.
