I used it (YankRing) for some time, but it was never consistent. The plus point is that it works across terminal, otoh often "p" did not work, so i would have to do "YRShow" and select.

Often this is used, but everything you delete gets copied to your clipboard.

       set clipboard=unnamed

So i prefer to map C-c and C-x (or whatever) to copy/cut to clipboard.

    " regardless of clipboard option, c-c copies selection to clip
    vmap <C-c> "+y
    " cut into clipboard
    vmap <C-x> "+d
    " copy to clipboard, http://news.ycombinator.com/item?id=4767227 , use 3 \y to copy 3 lines
    map <leader>y "+yy
    " paste from clipboard
    map <leader>p "+p
    " delete to black hole register, not going to clipboard etc
    nnoremap <leader>d "_d
    vnoremap <leader>d "_d

I've also mapped a key to write selected lines to a file, and another to read from it.

    map <silent> <leader>ww  :w! ~/tmp/vimxfer<CR>
    map <silent> <leader>wa  :w!>> ~/tmp/vimxfer<CR>
    nmap <silent> <leader>rr  :r ~/tmp/vimxfer<CR>
