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;

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

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
