I can find the up and down easily because they are shaped differently. They are the only keys split horizontally, and the connecting edges are curved inward unlike the other keys. I find them easy to feel fore. I am glad the new keyboard solves this problem for others though, I don't think the full-height left/right keys are particularly better.
