title: Javascript backspace functionality
body: <p>I need to implement the backspace key behaviour so that my cursor is placed one position to the left without the user pressing the Backspace key, but rather after a string is added programmatically inside my (contenteditable) div, I need the cursor to move automatically one position left. I tried adding <code>\b</code> to my string, with no success.</p>
  <p>How can I achieve this behaviour (preferably using JavaScript)?</p>
