How can I set text width and formatting a paragraph?

[Hector A. Abreu]

Hi,

The following is what I'm doing in Vim. I would like to do the same in 
Emacs Evil-mode. I am working in Org-mode:

1) In Vim I set the number of columns that I want for a specific paragraph 
that I will highlight to re-format:

:set tw=72

PROBLEM: In Emacs Evil-mode I get this message: State tw=72 cannot be set 
as initial Evil state

2) In Vim I highlight the paragraph with Visual mode (V and then j or k). 
Works ok in Emacs Evil-mode.

3) In Vim I type gq to put all the lines of the paragraph within the limits 
set on step 1. In Emacs Evil-mode apparently is putting the lines within 
the limits of step 1, but I am not sure since step 1 showed the message 
mentioned on step 1 for Emacs Evil-mode.

4) In Vim I type :runtime macros/justify.vim in order to be able to 
highlight the paragraph, and with _j put all the lines of the highlightd to 
end at the exact column number set on step 1, so the paragraph can look 
straight and aligned in the right margin. Nothing of this will work in 
Emacs Evil-mode, I guess because the Vim macros will not work.

I would like to be able to do this in Emacs Evil-mode. I am using Emacs 24 
on Debian Jessie (Raspbian Jessie Lite) on a Raspberry Pi, and I'm using 
Emacs Org-mode. I work via SSH. Below is my .emacs in case it provides any 
useful info for you to help me. Thank you in advance for any hint or info. 
Hector.
