Instead of choosing WPM from the outset from a drop-down, how about having a default start WPM and being able to change the WPM with keyboard shortcuts while you're reading? With this as in most reading I find myself slowing down in some parts and speeding up in others. With keyboard shortcuts one could keep one's eyes on the text while tweaking the speed. The keyboard shortcuts for the speed could be =/- or 0-9, like for the Autoscroll bookmarklet: http://tim.theenchanter.com/2008/08/autoscroll-in-safari-firefox.html http://tim.theenchanter.com/2008/08/autoscroll-in-safari-fir...
