There isn't a way to edit an email address on a key.  That is a
feature, for various reasons.  What you need to do is generate a new
address on that key, and then revoke the old address.  Some people
have many old addresses (revoked) on their keys.  Some people just
make a whole new key.  It's really a question of how easy it is in
your environment to make a new key, and whether you have signatures
(on the non-revoked user IDs) that you want to keep, etc.
