Thank you in advance

Cross my fingers refers to actually crossing your fingers, usually the middle finger over the index finger.
Crossing your fingers can have several meanings depending on context, most dealing with superstitions or children's games.

Very nice picture and completely accurate. I think that crossing one's fingers so that what you say doesn't count can also be explained as a way of lying, since you don't tell the other person your fingers are crossed. You cross them behind your back, usually. Am I telling you the truth? Cross my heart and hope to die. SS
