The interesting stuff only:

    set showbreak=>\ 
    set wildignore=*.bak,*.pyc,*.swp
    set wildmenu
    set wildmode=list:longest

This is actually quicker than reaching for ESC most of the time:

    inoremap <C-s> <ESC>
    vnoremap <C-s> <ESC>

Tab switching:

    noremap <C-l> gt
    noremap <C-h> gT

Something useful for syntax file writing:

    noremap <F6> :echo synIDattr(synID(line("."), col("."), 1), "name")<CR>
