No, you can't type from a wireless keyboard to an Apple TV. But hold on, if you have a iTouch, iPhone, or iPad you can get the app "Remote" on your device. When you download that, turn on "Home Sharing" on your Apple TV (it will say "Computer" as the selection in the selection area when you turn it on and will have a house on it) and enter the Apple ID you want for it to buy movies and what Apple ID you want it under as. When you do that, go to the Remote app on your mobile device and sign in on the same Apple ID. Wait while it loads. Then select your Apple TV. and now you can fully control your Apple TV with this app, it is your Apple TV remote but easer to use. To move the selection you swipe in the direction you want to go in, and when you run in to having to type, simply swipe right to move your cursor over the typing box and your keyboard will show up on your mobile device and you can type it faster (dont worry if it doesn't appear instantly on your Apple TV, it takes around 3 seconds)! You will also need the mobile device on the same Wi-Fi as the Apple TV.
