The editor ''nano'' is a free editor available on all unix systems.

It is not as good as e.g. emacs, but it is an ok alternative if you
must work on a remote machine and do not have the time to learning editors like emacs or vi.

To open it, open a terminal and write {{nano}}. To open a file called 
''file.txt'' in nano, write {{nano file.txt}}.

The two bottom lines of the window then contain the basic commands 
(__^G:__ means ''ctrl G'', etc.):

{{{
^G Get Help  ^O WriteOut  ^R Read File  ^Y Prev Page  ^K Cut Text    ^C Cur Pos
^X Exit      ^J Justify   ^W Where Is   ^V Next Page  ^U UnCut Text  ^T To Spell
}}}

Pressing __ctrl G__ gives a list of commands. 
The M in commands like __M-T__ refers to the META key.
On the Mac, you invoke the meta key by
''pressing the ESC key, and thereafter T'' 
(or whatever key is mentioned).

Useful commands when working with large files:

* __M-G__ =  Go to line number
* __^K__ = Remove ''the whole'' line (note: different from emacs and see)

To cut and paste text:

# Press __^A__ key
# Move to the end of the area you want to mark
# Press __^K__ to cut
# Move to where you want to paste it
# Press __^U__ to paste

The command {{info nano}} contains some, well, info.
