I have a bookmarklet that makes the Up arrow large enough to click on an ipad. ( http://news.ycombinator.com/item?id=1398539 http://news.ycombinator.com/item?id=1398539 ) I've adapted it to change your preference for the vector up: javascript:{im=document.images;iml=im.length;for(i=0;i<iml;i++) {if(im[i].src=="http://ycombinator.com/images/grayarrow.gif"){var old=im[i]; var p=old.parentNode; p.removeChild(old); iml--; p.innerHTML="▲"} } alert("Done"); void(null);} Down arrow left as an exercise
