Update PGP Key Info?

How do I edit my email address in a PGP/GPG Key?

I don't think you can. You can delete the user ID and create a new one with the new email address but according to the gnupg manual (http://www.gnupg.org/gph/en/manual.html) , it generally isn't a good idea to delete from your own key:

For local keyring management, deleting key components is a good way to trim other people's public keys of unnecessary material. Deleting user IDs and subkeys on your own key, however, is not always wise since it complicates key distribution. By default, when a user imports your updated public key it will be merged with the old copy of your public key on his ring if it exists. The components from both keys are combined in the merge, and this effectively restores any components you deleted. To properly update the key, the user must first delete the old version of your key and then import the new version. This puts an extra burden on the people with whom you communicate. Furthermore, if you send your key to a keyserver, the merge will happen regardless, and anybody who downloads your key from a keyserver will never see your key with components deleted. Consequently, for updating your own key it is better to revoke key components instead of deleting them.

You can create a subkey.
