http://askubuntu.com – Im trying to find how to something like : Control+z="<" Control+x=">" Is this possible? my keyboard doesnt have the ISO missing key that in Portuguese matches the <> key. the keycode for <> key is 94, being that without shift is <(less) and with shift pressed is >(greater) the keycode for control left is 37, Control_L the keycode for z is 52 and for x is 53. How can i do this using xmodmap: xmodmap -e "keycode 37 + keycode 52 = less" xmodmap -e "keycode 37 + keycode 53 = greater" (HowTos)
