Ingenious, fast way to find your files:

Command-T - Fast file navigation for VIM : vim online.

I use the following mappings:

" Set leader key to comma
let mapleader = ","

" Command-T shortcuts
nnoremap <silent> <Leader>t :CommandT<CR>
nnoremap <silent> <Leader>b :CommandTBuffer<CR>

Bring up the finder with ,t or "comma-t". Use the :CommandTFlush command to re-read directory.
