Indeterminism vs Sanchronic

i think the account of indeterminism is slightly off here. Indeterminism says, if i press paws right now, at this moment in time, what's going to hppen at the next moment? Well, nothing that's led up to this is going to determine that one outcome or another happens. So it's up to me, as an agent agent, to be able to pick which outcome comes about. But i don't think this actually gets rid of the difference making principle within it.
