An easy way to do it would be like this

TRichedit.SelStart := Length(TRichedit.Text);

To scroll 3 lines down:

RichEdit1.Perform(EM_LineScroll, 0, 3);


To scroll 3 lines up:

RichEdit1.Perform(EM_LineScroll, 0, -3);

Or

RichEdit1.Perform(EM_Scroll, SB_PAGEDOWN, 0);
RichEdit1.Perform(EM_Scroll, SB_PAGEUP, 0);
RichEdit1.Perform(EM_Scroll, SB_LINEDOWN, 0);
RichEdit1.Perform(EM_Scroll, SB_LINEUP, 0);

CrazyOne,
TRichedit.SelStart := Length(TRichedit.Text);
Doesn't seem to work when I am adding lines to the control in the OnActivate mehtod of the first form that is displayed by the application. i.e. before any user interaction has taken place. After that I don't need to do anything except give the control focus and it will follow (scroll) as I add ne lines.

Epsylon,
Thank-you your solution worked although on reading through some of the other messages I chose the EM_SCROLLCARET because I actually wanted to follow the cursor.
