With this check box selected, the scroll wheel (if any) will work in the opposite direction (so that if rolling the top of the scroll wheel towards you previously causes a scroll down, then it will now cause a scroll up). This may be useful to handle a unusual setup of the X server.
Check this item if you don't have a &MMB;. You can press the left and right mouse buttons at the same time to emulate middle-click.
Just tick the “reverse scroll direction” in your mouse settings (in the system settings under “Input Devices”). That did the trick, but not completely. It only seems to be applied for the Qt applications! Yay, we have a good old setting per UI Toolkit again… But that’s wrong., we have libinput now and we can set “natural sorting” there. Why isn’t the settings page doing that under the hood if libinput is being used? Anyway, the fix here (comes from this link) was to do:
xinput set-prop 11 282 1

pointing device.)</para>

The <guilabel>Adaptive</guilabel> profile is the default profile for all devices and takes the current speed of the device into account when deciding on acceleration. The <guilabel>Flat</guilabel> profile is simply a constant factor applied to all device deltas, regardless of the speed of motion.
