Richedit.Setfocus;

then each time you add, use:

SendMessage(RichEdit.Handle,WM_KeyDown,40,0);

Wait, I forgot to tell the lines are added from a TEdit control, but I want the Edit to keep focus (It's for a chat program -- My friends wanted colors in it :-). So I'd have to keep switching focus, right?

No you wouldn't have to change focus all the time. infact you don't have to use setfocus at all.

hi,

another way (sample)

you can use this to scroll one line

//Scroll Up
procedure TForm1.Button1Click(Sender: TObject);
begin
  richedit1.Perform(EM_SCROLL,SB_LINEUP,0);
end;

//Scroll Down
procedure TForm1.Button2Click(Sender: TObject);
begin
  richedit1.Perform(EM_SCROLL,SB_LINEDOWN,0);
end;
