How to import an email address into Contacts?

[Oldmanmac]

I just got an email where an email address was to be changed. I didn't have the original email, so it wouldn't be a change per se. But I DO want to add it to my 'Contact' list. Is there a simple answer?

Hover mouse over address, click arrow on right, add to contacts.
