Hi John,

If you need just one character on "Enter" then you can just handle PreviewKeyDown event on TextBox and paste following handler:

    private void Txt_OnPreviewKeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Enter)
        {
            var txtBox = e.Source as TextBox;
            var selectionStart = txtBox.SelectionStart;
            txtBox.Text = txtBox.Text.Insert(selectionStart, "\n");
            txtBox.Select(selectionStart + 1, 0);
            e.Handled = true; 
        }
    }
