Yes, exactly. Keyboard arrows, Numpad arrows, PgUp/PgDn, Home/End, hjkl, jikl, wasd - all have some kind of physical symmetry. There are even extreme cases like Truly Ergonomic Keyboard where block of arrows is fully symmetrical to block of PgUp PgDn Home End: http://www.keyboardco.com/keyboard_images/truly_ergonomic_computer_keyboard_209_large.jpg I guess such symmetry is key to ergonomics. -- Evgeny Panasyuk
