Mutt set up advice.

[Dan Hunt <dan@hunt.ath.cx>]

Would you care to offer any tips on customizing my favorite
mailer mutt? This image http://mutt.org/screenshots/pager.gif has some
buttons at the top that were set up in eterm.
How did they do that?
Would you like to show off your "Mutt super powers"? 
What customizations would you like to share?

I read this list and one or two others. I will be reading this 
http://codesorcerv.net/mutt/mutt-gnupg-howto to set up GnuPG with 
mutt. I also use mutt to access my imap work mail, but I do not know how
to edit the header to make the mail "come" from "me@work".
