Filetype recognition in Vim

If your LaTeX suite does not want to load when you create a new.tex file, it is probably due to the following line missing in the _vimrc file:

" Prevents Vim 7.0 from setting filetype to 'plaintex'
let g:tex_flavor='latex'

::call histdel("/", -1)|let @/=g:Tex_LastSearchPattern
