title: How to define customized command in cmd prompt for directory navigation?
body: <p>Say I want to navigate to a directory but don't want typing the directory every time. </p>
  
  <p>Is there a way to define a customized short keys in the cmd prompt like </p>
  
  <p><code>set root=C:\Users\sz\to\this\path</code></p>
  
  <p>So next time only typing <code>cd root</code> can direct me to the target root. I hope the short key will be stored permanently - when I re-open the cmd prompt, the short key is still valid. </p>
  
  <p>Even better, is it possible to define a short key that only typing <code>root</code> (without typing <code>cd</code>) can do the same thing? </p>
  
  <p>Thanks in advance!</p>
