For nowyou could use @Taifun 's TextBox extension and use Enter Pressed Listener or Set Icon for Enter button on soft keyboard for a textbox. In that way when enter pressed or Done create a procedure to display subtotal

You can't use plain App Inventor, but you can use Taifun's extension in conjunction with App Inventor since the TextBox Component doesn't have a .changed function
