FreeNAS

I did a forum search and found many mentions of the subject, but I have never seen any mention of it in the documentation. I did a search of the current documentation and found only one result:
http://doc.freenas.org/11/intro.html?highlight=midnight%20commander#u2
The above notice, included in the current release, advises that the version has been updated, but there is no other reference in the documentation that the software package exists.
I feel like that is something that should be in the documentation, that it exists and a little tutorial or a link to a tutorial, on how to use it.
There is a reference for tmux and I would say that this is at least as important, especially for new users.
