This is a way to transfer the ball from one flipper to the other after shooting a ramp.
you simply nudge straight up as the ball rolls down the flipper, and it goes onto the other one.

that said, you can only do it once per 30 seconds or so on keyboard, at least in tournament.

it sorta works from a trap but won't get you a clean catch on the other flipper.

this is something that still can't really be done in real life, but seems balanced currently.
