Its not so much about using n, p, f, and b as it is about keeping your hands in position above the home row. This is also why so many emacs users make Caps_Lock into a control key - easy access from the home row. The RSI angle is similar - moving your hand from the home row position to the arrow key cluster position _quickly_ often involves twisting ones wrist in a way that can exacerbate RSI problems. When youre primarily navigating around a buffer, you probably move your arm so that yours fingers rest naturally above the arrow keys, but if youre doing a lot of mixed typing and navigation, then youre more likely to be twisting your wrist to keep your hand nearer to that home row position (I think this is adduction/abduction, but my physiology classes were a long time ago). Early on, emacs users were especially likely to be using big battleship keyboards, with arrow key clusters so far away that moving the arm was required (lowering efficiency) or requiring a more severe twist to the wrist. I believe this is where the efficiency argument comes from, but thats just a theory. Hope that helps, ~Chad
