title: Delete whitespace in Visual Studio Code in arbitrary selection (aka join words) (not trim trailing whitespace)
body: <p>It seems like this should be a simple question, but I can't figure out how to delete all the whitespace within an arbitrary selection in Visual Studio Code (another way of saying this is to join all characters within a selection).</p>
  
  <p>Note: I'm not asking how to trim trailing whitespace although this function could be used to manually to that.</p>
  
  <p>It seems like there should be a built in way to do this, but if there isn't can someone point me to an extension that will do this?</p>
  
  <p>I wasn't able to find one yet.</p>
