GVIM is a very powerful editor. Proper configuration helps you to unleash its power.

I normally use the following configuration file .gvimrc which is to be
placed in your home directory:

syntax on
set nocin
set nosi
set autoindent
set shiftwidth=2
set textwidth=75
set ic
set hlsearch
set columns=80
set lines=40

function Bracketsub()
s//\>/g
endfunction


Some more options that may be useful
syntax highlighting
nocin - no C indenting
nosi - no smart indenting
autoindent
shiftwidth
textwidth
ic - ignore case
hlsearch - search hightlighting
