Hi Jeroen Barnhoorn,

I tried it and it works. However, it says that it is deprecated, would it be a problem in the future?

Would it be a problem? Probably not, at least not for the foreseeable future. 
However, it would indeed be better to use keydown and key instead:

document.addEventListener('keydown', function enterPress(e) {        
    if(e.key == 'Enter') {                
        $actions.ScreenAction();        
    }
});

Thank you
