Had one's fingers crossed (5)
I believe the answer is:
hoped
'had one's fingers crossed' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hoped that I've seen before include "Desired with the expectation of success" , "and 25: Anticipated" , "Desired, trusted" , "Desired, with optimism" , "Aspired" .)
