Default [Q] CM9 Keyboard Backlight Duration

Hi Everyone,

I've checked around this message board and the web and haven't found much info. I'd like to be able to extend the duration the keyboard back-light is on for at least a few more seconds but have not been able to find much other than the ability to enable/disable it. Sometimes, I'll get part way through a text message and if I have to stop and think about what I'm going to type, the light goes out within a few seconds. I've also searched through as many settings on the phone as I could think of and haven't found any that could change this. I'm running CM9, alpha 4. Can anyone provide some insight on if it can be changed or if there even is a setting that can do this?

Thanks!
