VI and MAILX (was: Re: question about vi)

[Mario Dorion]

[ when entering mail in mailx, ~v at the beginning of a line
  will invoke the editor named in the VISUAL variable.
  Dave Decot suggests this alias: ]
>
>alias mailto 'vi /tmp/mail.$$ && | /usr/bin/mailx \!* < /tmp/mail.$$'
                                                     ^^^

Can someone explane to me what does this \!* mean!
