pgp encryption problem

Where the recipient email is not matched to pgp key id, aerc refuses to encrypt. It would be more helpful to list available gpg keys to encrypt to using up/down arrows. This assists when using alias services such as addy.io where recipient email won't match their pgp key id Fairmail android allows this on the fly. thunderbird allows this with json alias configuration but not on the fly like fairmail android which is better. thanks
