"Available" can mean available from a Debian managed repository, which
probably includes all the installed packages on your machine and all
that you have not installed as well. To get the complete list use '~T'

OT: while checking my memory on this, I noticed a plaintive question
from 2007 about the "Aptitude Reference Manual" which seemed to be
mentioned in Debian documentation but seemed not to exist. My quick
search indicates that this situation still exists in 2011. The
aptitude man page references 'Aptitude Reference Manual' but I get no
hits for that string while searching www.debian.org, or googling the
general web (other than questions about where to find it, over the years).

I did find 
which contains a long list of aptitude regex formulae.
