[SM]Locking input?

I know there's a way to do this in 3.9 but i'm not sure how...

how would one go about locking or disabling input keys on any said screen in a theme?

[02:47:43] |Steve|> That screen just hangs out for a few seconds.
[02:47:56] |Steve|> I think it queues input.

that would be ScreenStage... it works as far as locking keys; but I can't get an animation to come up :|

[ScreenBoot]
Class=ScreenStage
Fallback=ScreenAttract
NextScreen=ScreenKonami

I get a black screen with a pink cube in the top right corner...
