swithching to nvim (neovim). thanks @hipster

angelo@~$ which nvim
/usr/local/bin/nvim
angelo@~$ sudo ln -s /usr/local/bin/nvim /usr/local/bin/iv
Password:
angelo@~$ iv
angelo@~$

yet, i used to use `vi` on my linux mint laptop.. so it s hard - `nvim` keybindings are different from `vi` - and also i m almost noob in that editors
