- Ideally, no mapping is necessary; controls should be naturally suited to their application. The problem here is that scrolling is designed for homogeneous content (such as a long column of static text), while web pages increasingly have heterogeneous media. Rather than try to rewire the controls, it’s easier to adapt the content so that it fits the controls we have. By limiting the visual changes and by retaining normal scrolling text, we are less likely to harm usability.

- I’d like to have access to touch events in desktop, for one, so that I could know whether the fingers are down (on track pads and magic mice, e.g.). And I always thought chording keyboards were a cool idea (particularly after observing court stenographers), but never seriously tried one. And maybe some standardization of swipe events on mobile.
