Debian, Vim and alternatives

I don't know why, but default editor in Debian is not Vim, but Nano. I learned once that it can be change with a command, but has never remembered the actual name of it and since than had to check it each time in install Debian (not so often). Today decided to write it down, not to search too long next time. Maybe it's going to be useful to others:

aptitude install vim.nox
update-alternatives --set editor vim.nox
