You CAN use the "OnKey*" events for this, trapping a complex keystroke
looks something like:
procedure TForm1.Memo1Keydown(Sender: TObject;
var Key: Word; Shift: TShiftState);
begin
if (Key = Ord('S')) and (Shift = [ssCTRL, ssShift]) then...
end;
But as another poster pointed out, it's much easier to work with Actions.

If you're 100% sure you're not setting SelText somewhere then my first
guess is that something is "typing" into the Memo, which serves to clear
the selected text.
Post your current key handling code, it will probably show up there.
