Walkthrough of Usage
To use the addressbook, hit 'a'. Accept the given alias, or replace with your own.
Confirm the address.
Give the contact a name. The name can contain spaces.
Accept the entry.
Finally, confirm the alias file.
After doing this a few times, it will become second nature to hit <Enter> through most of the steps.
To access the mutt addressbook, hit <Tab> at the to, cc or bcc line. You will be presented with a list of aliases from your ~/.mutt-alias file.
