Simulate keypress event in Javascript or Jquery

Question

I want to simulate keypresses in Javascript. There are no listener for those key presses. For example: The function will trigger key '32' (spacebar) and this should result in scrolling of page like pressing normal spacebar.

I tried keypress trigger from Simulating a Keypress Event from Javascript Console but it didn't worked.

Edit
Key presses are not limited to spacebar only. It can be combined keys like alt+Ctrl+D and the browser should respond to them like keypresses from physical keyboard.

If you're only looking to scroll the document, you can approximate a Spacebar or Pg Dn scroll by using 85% of window.innerHeight - no jQuery needed:

window.scrollBy(0, window.innerHeight * .85);

Scrolling was just an example to illustrate the point. The requirement is general.

By this way you can bind keypress event to body and identify which key is pressed.

jQuery('body').on('keyup',function(e){ 
     if(e.which == 32) {
          // spacebar pressed, your scroll code here.
     }
}) ;
