Reverse Scroll on Fedora 18

Check your mouse ID by typing:

xinput --list


It will show a list something like this:

� Virtual core pointer                     id=2 [master pointer  (3)]
�   ��� Virtual core XTEST pointer               id=4 [slave  pointer  (2)]
�   ��� Microsoft Microsoft�� 2.4GHz Transceiver v7.0 id=9 [slave  pointer  (2)]
�   ��� Microsoft Microsoft�� 2.4GHz Transceiver v7.0 id=10 [slave  pointer  (2)]
� Virtual core keyboard                   id=3 [master keyboard (2)]
    ��� Virtual core XTEST keyboard             id=5 [slave  keyboard (3)]
    ��� Power Button                             id=6 [slave  keyboard (3)]
    ��� Power Button                             id=7 [slave  keyboard (3)]
    ��� Microsoft Microsoft�� 2.4GHz Transceiver v7.0 id=8 [slave  keyboard (3)]



After you get the mouse ID, then type this command to make the mouse scroll reversed:

xinput set-button-map 1 2 3 5 4
