How to use the format.blockquote function in format

this.container = element;

  this.caret = new Caret(content);

  // fix keyboard behavior
  var k = require('k-format')(content, {caret: this.caret});

  setupToolbar(this);

  var buttons = toolbar.getElementsByTagName('button');
  events.bind(content, 'click', refreshStatus(buttons));
  events.bind(content, 'keyup', refreshStatus(buttons));
  events.bind(toolbar, 'click', refreshStatus(buttons));
  k('super+b', format.bold);
  k('super+i', format.italic);
  k("super+'", format.blockquote);
  k('super+l', function(e) {
    e.preventDefault();
    if (!k.alt) {
      format.ul();
    } else {
      format.ol();
    }
  });
}

setTimeout(function() {
        format.blockquote();
        format.p();
      }, 1);
      return true;
