title: How to make vscode compact multiple lines to a single line?
body: <p>I have 4 lines like this in vscode:</p>
  <blockquote>
  <p>1 line;<br />
  2 line;<br />
  3 line;<br />
  4 line;</p>
  </blockquote>
  <p>Does vscode have a shortcut that can quickly compact 4 lines to 1 line like this:</p>
  <blockquote>
  <p>1 line;   2 line;  3 line;   4 line;</p>
  </blockquote>
