This is probably my most trivial greasemonkey script yet, but perhaps the most useful...upanddownpage lets you use one hand to page up and page down on macs. Again, the code is very trivial, but I find myself doing something with at least one hand (insert dirty jokes here), like playing guitar or writing, while I'm looking at a web page; and I don't want to use both hands to just page up or page down. Normally it's fn+up and fn+down -- fn on the far left, up/down on the far right, and this is a pain. You can switch tabs, go back, go forward, go up, go down, go to page end, and go to page start with one hand -- it's just inconsistent to exclude page up and page down. And, yes, it's utterly trivial: 
window.addEventListener('keydown',function(e) {
    if      (e.keyCode == 38 && e.altKey) window.scrollByPages(-1);
    else if (e.keyCode == 40 && e.altKey) window.scrollByPages(+1);
  },true);
Oh yeah, happy new year.
