Implementing block indent/unindent in Tmemo

Hello,
I am trying to implemement a block indent/unindent routine in a Tmemo; so for eg, when pressing a hot key (say ctrl+U/I) the selected text moves left/right one tab space. Funny thing is that it works like so in a TRichedit:
---------------------------------
procedure TForm1.ToolButton15Click(Sender: TObject);
begin
if richedit1.Paragraph.FirstIndent>=10 then
richedit1.Paragraph.FirstIndent := richedit1.Paragraph.FirstIndent-10
end;
-----------------------
But tying to get it to work in Tmemo is doggin me :(
Many thanks in adv,
omziff

well,
a tmemo is not a trichedit
and has no paragraph-property

you have to insert some blanks or a tab
to each line at front to simulate an indent
