  ;; The third number is the minimum distance traveled per interval in pixels.
  ;; The fourth number is the maximum distance traveled per interval in pixels.

  ;; Mouse wheel actions.
  ;; The first number is the interval in milliseconds between scroll actions. ;; The second number is the distance in some arbitrary unit. Play with the parameters to see what feels correct. Both numbers must be in the range 1-65535
  ;; In both Windows and Linux, 120 distance units is equivalent to a single notch movement on a physical wheel. In Linux, not all desktop environments
  ;; support the REL_WHEEL_HI_RES event so if you experience issues with `mwheel` actions in Linux, using a distance value that is multiple of 120 may help.
