Use pygame.KEYDOWN and pygame.KEYUP to detect if a key is physically pressed down or released. You can activate keyboard repeat by using pygame.key.set_repeat to generate multiple pygame.KEYDOWN events when a key is held down, but that’s rarely a good idea. Instead, you can use pygame.key.get_pressed() to check if a key is currently held down:
You probably forgot to give # before id for id selector, you need to give # before id ie is ulIdYou probably need to bind the scroll event on the div that contains the ul and scrolls.

stopPropagation prevents further propagation of the current event in the capturing and bubbling phases. preventDefault prevents the default action the browser makes on that event. Examples preventDefault stopPropagation With stopPropagation, only the button‘s click handler is called while the div‘s click handler never fires. Where as if you use preventDefault, only the browser’s default action is stopped but the div’s click handler still … Read more
Not all browsers support event capturing (for example, Internet Explorer versions less than 9 don’t) but all do support event bubbling, which is why it is the phase used to bind handlers to events in all cross-browser abstractions, jQuery’s included. The nearest to what you are looking for in jQuery is using bind() (superseded by on() in jQuery 1.7+) … Read more
