Switching to new key after accidental key revocation

[danielhatton]

I've been using Password Store happily for some time (thanks all developers!), with the password store in a local directory, and the OpenKeyChain authentication mode. Unfortunately, I had a little accident in OpenKeyChain and revoked the key I'd been using for Password Store. As a result, I can't add any new passwords to the store (although I can still access the passwords that were already in there). I've created a new key in OpenKeychain (and added it to the authorized_keys file of the local SimpleSSHD ssh server), but I can't find anything in the Password Store documentation about how to get Password Store to migrate to using the new key. Please advise.
