So my Surface was asleep, in laptop form (kickstand out keyboard laying flat) I went to press the windows key to wake it up and stopped to do something else quickly, realized the keyboard was lit up. Not sure why it never went to sleep like the tablet did, but I waited and sure enough the keyboard finally did go off. then I hovered my hand over it, like 5 inches above it, sure enough, it lights up. How in the world does it know this? I know my GS4 has that hover feature, but the keyboard?
