Hi, I have acer v3-571g laptop with elan touchpad v3. (1)When I use v2.1.3 drivers on my laptop ,I can use fn+f12 and fn+Ins to change brightness. But after that version it does not work.Can you tell me how to make it works again when I use the 3.0.2 drivers? (2)In my keyboard ,fn+arrowup and fn+arrowdown is used to change brightness . I changed fnkeys mode to 1 and changed arrowdown to brightnessdown ,so I can use fn+arrowdown to keep brightness down.But there is not an arrowup to use in info.plist of keyboard controller. Can you add arrowup to the info.plist ? I am using mavericks and mountainlion. Sorry for my bad English .
