/**
* This method can be overridden to handle various user input (mostly from the keyboard) when this component is in
* focus. The input method from the interface, {@code handleInput(..)} is final in
* {@code AbstractInteractableComponent} to ensure the input filter is properly handled. If the filter decides that
* this event should be processed, it will call this method.
* @param keyStroke What input was entered by the user
* @return Result of processing the key-stroke
