I've created following xmodmap file:
keycode 64 = Mode_switch (right Alt key) keysym j = j J Left keysym l = l L Right keysym i = i I Up keysym k = k K Down
it works almost great, but. In polish programmers layout R_Alt + L stands for "Ł". When I'm applying file above R_Alt + L doesn't works. What should I change to have working both - R_Alt + L & L_Alt + L?
