For those using VIM, I have some cool settings for you to try if you do a lot of config and source editing.
Make (if there is not one already) a ~/.vimrc file.
Edit it with...
What it basically does is it turns on keyword coloring (you can change delek into any other colorscheme), line numbering, a tabwidth of 4 and allows you to properly backspace your lines, etc. Put it on and try it out.
