How to use keyboard for Injustice (PS3)

[BrianTheBEAST]

I've seen other forums discussing this, but they never really said how to even connect the keyboard to injustice. My keyboard is connected to the PS3 btw; it just doesn't work for Injustice

The game has to support the Keyboard and Mouse, and I don't think Injustice supports it.
