gpg2 --quick-add-uid user-id new-user-id
supports the specification of the key by using an unambiguous part of the uid.
gpg2 --quick-add-key fpr [algo [usage [expire]]]
currently only works using the full fingerprint.
Could you please add these form of specification to it so it is not necessary to type the whole fingerprint?
The fingerprint is required because that is the unique identifier for a key. Without that we would need to presetn a menu to select between keys. This would make scripting complicated again. On the command line c+p is easy enough to hget the fingerprint. c+P is also the reason why we print the fingerprint by default without spaces.
So sorry, this will not be changed.
