I am referring this... When you run gpg --fingerprint, you'll see
something like this:

pub   ..../..... ....
      Key fingerprint = ....
uid                  name (I mean this field.) <email @ mail.com>
sub   ..../... ...

I don't understand what you mean by that sentence.

Notations and comment part of a user ID are different things?

I guess I prefer the comment part of a user ID, because that is shown by
default. (The --list-options show-notations does not seem to be very
popular.)

Is it possible to add a comment to the user ID of sub keys?
