Not sure what you really want, but you can test for a Enter key in your forms onKeyDown event

 procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
 if key = VK_RETURN then beep();
end;

Button1.Default := True
All other buttons on a form should have Default := False

Set the focus on the button you want like :

Button1.SetFocus

When you now press the enter key you'll get the normal button's 'on click' event.

If You've got four edits and two buttons on a form.
You can do like this. If I understand what You mean.

procedure TForm1.Button1Click(Sender: TObject);
begin
  Edit3.Text := Edit1.Text;
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  Edit4.Text := Edit2.Text;
end;

procedure TForm1.Edit1Enter(Sender: TObject);
begin
  Button1.Default := True;
end;

procedure TForm1.Edit2Enter(Sender: TObject);
begin
  Button2.Default := True;
end;

procedure TForm1.Edit1Exit(Sender: TObject);
begin
  Button1.Default := False;
end;

procedure TForm1.Edit2Exit(Sender: TObject);
begin
  Button2.Default := False;
end;

procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
 if key = VK_RETURN then Button1.click;
end;

OR

procedure TForm1.FormKeyPress(Sender: TObject; var Key: Char);
begin
 if (Ord(Key) = VK_RETURN ) then Button1.Click
end;

Set forms KeyPreview = true
