But PGP also need From: address or sender's key to encrypt messages, sign messages or even attch their own public key. By default, mutt uses system default key or oldest key created for encryption, sign messages or attach public key.

It is probaby a good idea if mutt has an option to show a list of all PGP  keys that people can choose from, as From: or sender's key to sign, encrypt or attach,  every time they compose a PGP message, if they have multiple email accounts. 

Such option may even also be good for choosing recipient key because some people use PGP keys that are different from their email address.
