I am not sure that I completely understand your question, as this is such a
simple process.

Assume you are talking about deleting a contact from your contact list? Not
sure what each letter of the alphabet has to do with it.

Simply click the name/contact you want to delete and either hit the Delete
key OR right click and select delete.

Be sure it is the right one, as there is no confirmation window. However,
if you delete the wrong one, go the Deleted Items folder and undelete it.
