Fire Button's onAction with Enter in JavaFX

Question

I'm a newbie to JavaFx. In my JavaFX application I have set onAction property and it works fine when I press the button using mouse. I want to fire the same even when user press Enter on button. I know I can use a even handler to do that. But when I read the onAction JavaDoc it says that this event get fire by a key press.

Property description:

The button's action, which is invoked whenever the button is fired. This may be due to the user clicking on the button with the mouse, or by a touch event, or by a key press, or if the developer programmatically invokes the fire() method.

But when I press Enter key nothing happens. Is it error in documentation? Are there any other way to achieve that without adding alistener to the button?

P.S

After the comments I checked with space key then it get fired. But I want to set that to Enter key. I have many buttons. I tried button.setDefaultButton(true); but it is not get fired. I think that is becacuse there are more than one button. If I set it just to a single button it works fine. How to set that to multiple buttons?

You can dynamically change the default button property of the currently focused button by using binding

btn.defaultButtonProperty().bind(btn.focusedProperty());
