What's a nice way to say "fingers crossed"? What's a nice way to express any of the following - * "Let's keep our fingers crossed" * "I'll keep my fingers crossed!" * (We / I) (are / am) keeping (our / my ) fingers crossed"

Of course not all cultures cross fingers when wishing for something. As far as I know crossed fingers don't signify anything in Japan.

The phrase "fingers crossed" would probably expressed using "to go well", e.g.

>
> ()

where the former is more formal and the second more conversational.
