title: How do I duplicate a line or selection within Visual Studio Code?
body: <p>Using Microsoft's Visual Studio Code, how do I duplicate a line of code and then move it up and down? (Similar to Sublime's <kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>d</kbd> behaviour)</p>
  
  <p>It's a feature that I use constantly, and am struggling using Visual Studio Code without it.</p>
