Comment 5 for bug 127514

If apps should use 6 and 7 for vertical scroll, let them do so. I don't know any application that would scroll vertically now, e.g. Nautilus displays a right-click menu instead. Make buttons 8 and 9 standard back and forward buttons all across Ubuntu. My grandma doesn't want to install scary apps and run scary commands to configure something trivial. She wants to use her mouse, with the buttons on it working.
