How to change the scrollbar position in a non-focused TMemo

Answer:

You'll have KeyPreview set true of course then:
1   
2   procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word; Shift: TShiftState);
3   begin
4     case Key of
5       VK_Down: Memo1.Perform(Messages.EM_LINESCROLL, 0, 1);
6       VK_UP: Memo1.Perform(Messages.EM_LINESCROLL, 0, -1);
7       {and if HorzScrollbars are also used}
8       VK_Left: Memo1.Perform(Messages.EM_LINESCROLL, -1, 0);
9       VK_Right: Memo1.Perform(Messages.EM_LINESCROLL, 1, 0);
10    end;
11    {But where is the focus when you are doing this? Do you want the keystroke passed
12    elsewhere? If not then}
13    Key := 0;
14  end;
