My .vimrc

Below goes my fairly humble .vimrc. This post acts primarily as a handy backup for myself and secondarily is yet another .vimrc shared in the wild (I've learned a lot on those).

"enabling 256 colors required by zenburn
set t_Co=256

" zenburn colorscheme (make sure ~/.vim/colors/zenburn.vim exists)
colorscheme zenburn

" better current tab color
hi TabLineSel ctermbg=102

My configuration is fairly vanilla, no plugins and the only external file is for the zenburn color scheme.

The unique thing about it is how I remap the arrow keys. Left and right for tab navigation. Down closes tab. Up opens a new tab with Netrw for file browsing (who needs NERDTree?).
