Questions on Wake Up Attacks

[Magna]

How are you supposed to do wake up attacks? Do you need to imput the command before reaching the ground, as soon as you hit the ground, or if you stay down you can use it anytime to get up?

Also, all wake up attacks works with enhanced attacks?

What about X-Rays? Do some or all of them work as wake up attacks?

And one last question, what are the other possible ways to recover after hitting the ground?

You have to time the input of the move you're trying to wake-up with so that is ends right when your character stands up. Only certain moves can be used on wake-up, but they're pretty easy to do once you get the timing down.
