I'm wanting to pair my iMac's keyboard with my iPad for those times I'm away from my desk. When I turn my iPad's bluetooth on, it doesn't discover my keyboard. In fact, my iMac doesn't even show up on my iPad even though it's set on discoverable. Maybe I don't understand how all this works. Could anybody explain how to pair my Apple keyboard to my iPad? Also, not sure I'd ever do it, but can you pair a mouse to an iPad? Any info would be greatly appreciated. I'm an old fart who's trying to learn this stuff.
