I'm looking for the event scripts for the open/close of the keyboard and the camera shutter.

I'd like to modify the events, specifically I'd like the camera app to not open automatically when the shutter is opened (as I've found it has a tendency to do while in my pocket) and I'd also like to change the keyboard so it doesn't automatically unlock the screen when it's opened.

Given its Linux roots I'm guessing there must be something similar to the udev rules when devices are connected/disconnected (I hope)

Thanks
