Right now, we have no way for the user to control the game. We will use the onKeyPress() method provided by the dart:html:Document object to handle key press events and make the DOM react. 
• Just like as the timer, we need to create a callback function. It will be called every time the user presses a key. It will add a paragraph element to the game board 
• We will register this callback function with the DOM using the document.onKeyPress() method 
• We will run our project and verify that each time a key is pressed, a paragraph element is added to our board element
