This command revokes a user ID on an existing key. It cannot be used
to revoke the last user ID on key (some non-revoked user ID must
remain), with revocation reason ``User ID is no longer valid''. If
you want to specify a different revocation reason, or to supply
supplementary revocation text, you should use the interactive
sub-command @code{revuid} of @option{--edit-key}.
@item --change-passphrase @var{user_id}
@item --quick-set-primary-uid @var{user-id} @var{primary-user-id}
@opindex quick-set-primary-uid
This command sets or updates the primary user ID flag on an existing
key. @var{user-id} specifies the key and @var{primary-user-id} the
user ID which shall be flagged as the primary user ID. The primary
user ID flag is removed from all other user ids and the timestamp of
all affected self-signatures is set one second ahead.
@item --change-passphrase @var{user-id}
@opindex change-passphrase
@itemx --passwd @var{user_id}
@itemx --passwd @var{user-id}
@opindex passwd
Change the passphrase of the secret key belonging to the certificate
specified as @var{user_id}. This is a shortcut for the sub-command
specified as @var{user-id}. This is a shortcut for the sub-command
@code{passwd} of the edit key menu.
