Answer 1

I believe that you need to accomplish this in a WindowsForms application to both implement the following method in your Form:

  protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if (keyData == Keys.Tab) { textBox1.Text += "\\t"; // Set the selection on the end of text. textBox1.SelectionStart = textBox1.Text.Length; textBox1.ScrollToCaret(); return true; } 

        return base.ProcessCmdKey(ref msg, keyData);
    }

You can use a javascript for this

    textarea.observe('keydown', function (e) {
  if(e.keyCode==9) {
    e.element().insert("\t");
    e.stop();
  }
}
