Stop having to write code like this
$(document).keydown(function(e){
if (e.which == 13) //enter
reloadResults();
else if (e.which == 37) //left arrow
previousPage();
else if (e.which == 39) //right page
nextPage();
});
And write this instead:
$(document)
.onEnterKeyDown(reloadResults)
.onLeftArrowKeyDown(previousPage)
.onRightArrowKeyDown(nextPage);
