Alternatively, you can simply highlight the email address and Command-C to copy, then open Address Book and manually add it by pasting it in a new or existing contact.
Do you mean contacts in Address Book? If so, simply click on a contact and press the delete key. To edit a contact, click on the contact, then click the Edit button at the bottom of the window. Or click Edit > Edit Card. Or press Command-L.
Press Command+spacebar. Type "Address Book" in the Spotlight search bar in the upper right corner of your screen. You will see "Address Book" beside the word "Applications". Click that.
I hate to be such a PITA But when Do as you say and try to paste the new address,it says Export vcard>edit card then a drop down menu asks Save as.
BTW: I will read Helpful info. It looks to be very informative.
