title: How to create a directory using nerdtree
body: <p>I have been using NERDTree for a while. Every time I need to create a new directory I need to go to terminal. Is there a quick and easy way to create a directory using NERDTree. </p>
  
  <p>I read the <a href="http://github.com/scrooloose/nerdtree/raw/master/doc/NERD_tree.txt" rel="noreferrer">doc</a> but could not find anything.</p>
