MouseWheel is not a default event within jQuery, so to start with you would need something like this and either write your own function to switch to the next page or use another plugin like scrollTo
Not quite sure whether or not that is best practice though..
EDIT
Here is a fiddle on the base of Stano's fiddle.
$("body").mousewheel(function(event, delta, deltaX, deltaY) {
event.preventDefault();
if (delta > 0 && current_page > 0) {
current_page = current_page - 1;
$("body").scrollTo( '#page_'+current_page);
} else if (delta < 0 && current_page < 10) {
current_page = current_page + 1;
$("body").scrollTo( '#page_'+current_page);
}
});
and another edit: the fiddle only works in FF as Chrome and IE refuse to load the scripts because of the wrong MIME-Type..
