title: Refactoring in Vim
body: <p>Of course the fact that you can refactor on IDEs is priceless for many, I hardly ever do it when I am coding but I may try to do it when editing some one else's source. How do you accomplish such a trivial task across multiple files in Vim?</p>
  
  <p>I found <a href="https://github.com/ecomba/vim-ruby-refactoring">this plugin</a> for refactoring Ruby, but how about "any" language?</p>
