Speed reading is training your field of view. I would agree that speed reading code is not really useful (even though skimming code looking for interesting stuff is), but what is immensely useful is being able to notice changes on your screen in general. Did something go from green to orange in your IDE? Was there an interesting keyword in the logs flowing by? Did this icon just blink? Has this counter just gone up?

I'm often astonished by the stuff people don't see on their screens when helping them debug something. Replying to "how did you know?!" by pointing to the edge of the screen where some small blob went from green to orange or to red is something that happens more often that I'd expect.
