Currently I'm using Xmodmap to reverse scrolling direction:
pointer = 1 2 3 5 4 7 6 8 9 10 11 12
What is the equivalent way to do this with xkb? (or is this possible at all?) I'm evaluating KF5 and realise that Qt 5 doesn't respect xmodmap configuration.
libinput
handles such feature with current releases.
