# How to totally close all the auto indent

In my case, I was writing a tex file. After Closing some auto indent settings

set noai noci nosi
filetype indent off
filetype plugin indent off

But vim still gave me 2 tab indent when I type { or [ in a 2 level \begin, like:

\begin{...}
\begin{...}
{
\end  {...}
\end  {...}

It is also shown in the picture, at line:55, the second \umlcreatecall.

I want no any auto indent, what will create it and how can I close it?

Thanks.
