New Keyboard Questions

[beta-user]

And as if by magic I see a Tweet saying the phone needs to be powered off before setting it in the case - problem solved :-) But I'd still like to know how to check they keyboard battery etc?

Do you have to reboot the phone each time you want to put on the keyboard case? Because that would make the keyboard much less useful in my opinion and I didn't see it mentioned in the store page.
