   * It accepts input in the form of
   * <code class="property">type "foo" on typewriter</code> where "foo" is a
   * string with quotes around it. Keyboard can have its
   * <code class="property">typing_target_id</code> set to an
   * {@link adventurejs.Asset|Asset} with its
   * <code class="property">is.typing_target</code> property set to true,
   * and the input string will display on it. See the following
   * transcript to get an idea how this plays out.
