I am using next code on to write some text in TRichedit. And caret is positioned on after the last string of the text. So my question is how to move it to the beginning of the next line?

        richedit1.Lines.Add(' ');
        AddColorLine(RichEdit1, DateTimeToStr(Now)+'  '+ loginmy,form2.SelectedSb.Font.Color );
         richedit1.selstart:=length(RichEdit1.Text);
   
procedure tform2.AddColorLine (RichEdit : TRichEdit; Str : String; Color : TColor);
var
  pos_start      : Integer;
  pos_end        : Integer;
  old_SelAttr    : TTextAttributes;
begin
  // take the old SelAttributes
  old_SelAttr := RichEdit.SelAttributes;
  // get the end pos
  pos_start := length(RichEdit.Text);
  // add the text
  RichEdit.Lines.Add(Str);
  // the the new end position
  pos_end := length(RichEdit.Text);
  // colorize the text
  RichEdit.SelStart := pos_start;
  RichEdit.SelLength := pos_end - pos_start;
  RichEdit.SelAttributes.Color := Color;
  // put back the old attributes
  RichEdit.SelAttributes := old_SelAttr;
end;

Use this
procedure tform1.AddColorLine (RichEdit : TRichEdit; Str : String; Color : TColor);
var
  pos_start      : Integer;
  pos_end        : Integer;
  old_SelAttr    : TTextAttributes;
begin
  // take the old SelAttributes
  old_SelAttr := RichEdit.SelAttributes;
  // get the end pos
  pos_start := length(RichEdit.Text);
  // add the text
  RichEdit.Lines.Add(Str);
  // the the new end position
  pos_end := length(RichEdit.Text);
  // colorize the text
  RichEdit.SelStart := pos_start;
  RichEdit.SelLength := pos_end - pos_start;
  RichEdit.SelAttributes.Color := Color;
  // put back the old attributes
  RichEdit.SelAttributes := old_SelAttr;

  RichEdit.SelStart := length(RichEdit.Text);
end;

Add setfocus as well
procedure tform1.AddColorLine (RichEdit : TRichEdit; Str : String; Color : TColor);
var
  pos_start      : Integer;
  pos_end        : Integer;
  old_SelAttr    : TTextAttributes;
begin
  // take the old SelAttributes
  old_SelAttr := RichEdit.SelAttributes;
  // get the end pos
  pos_start := length(RichEdit.Text);
  // add the text
  RichEdit.Lines.Add(Str);
  // the the new end position
  pos_end := length(RichEdit.Text);
  // colorize the text
  RichEdit.SelStart := pos_start;
  RichEdit.SelLength := pos_end - pos_start;
  RichEdit.SelAttributes.Color := Color;
  // put back the old attributes
  RichEdit.SelAttributes := old_SelAttr;

  RichEdit.SelStart := length(RichEdit.Text);
  RichEdit.SetFocus;
end;
