I can confirm this method: http://shkspr.mobi/blog/2011/12/changing-the-microsoft-4000s-zoom-keys-in-ubuntu/ NO longer works in 13.04 which is very annoying so I will be updating to 13.10 to see if that has been fixed, if not I will be down grading to 12.10. I will inform you of my findings. sudo evtest /dev/input/event5 with 13.04 still shows up nothing with Favourite Keys 1 - 5 still not working. Regards, John From:
