Hiding Scrollbars
To hide scrollbars from specific div elements or the entire document body, employ the following CSS rule:
overflow: hidden;
This will effectively conceal any scrollbars for the targeted element.

$("#example").bind("mousewheel", function(ev, delta) { var scrollTop = $(this).scrollTop(); $(this).scrollTop(scrollTop - Math.round(delta)); });

To emulate scrolling via arrow keys, bind a "keydown" event listener to the document (if needed) and adjust the scrollTop and scrollLeft accordingly. Remember to use "keydown" instead of "keypress" due to IE compatibility issues.
