editing User ID

[rick]

In setting up a user I managed to fat finger the email address.
The pgp documentation shows how to edit the user information using the -ke 
(key edit) flag, but I am unable to find a similar capability in gpg.  I 
thought that possibly I could remove the user id, then recreate the user 
with the corrected email address but I was unsure if I could retain the 
ability to decrypt existing files.

Is it possible to edit the user information in pgp?  Can someone point me 
to the applicable documentation for this item?

Thanks
