Since no one is going to produce a keyboard which provides numerable keys within the range of the thumb, thus removing the need to leave the home row, allow me to somewhat remedy my misery by adding the following 7 lines to my .xmodmap file:
keycode 133 = Mode_switch Mode_switch keycode 31 = c C Left keycode 32 = r R Right keycode 45 = t T Down keycode 46 = n N Up keycode 44 = h H Home keycode 33 = l L End
keycode 133 is the start key located on the lower left of a TypeMatrix 2030 keyboard. It’s still a long way away from the home row but it seemed to be the most viable candidate by allowing at least one hand to stay on the home row (Dvorak layout).
