What is the standard of review applied by the Court of Appeal in determining whether to instruct a jury?

"An appellate court applies the abuse of discretion standard of review to any decision by a trial court to instruct, or not to instruct, in its exercise of its supervision over a deliberating jury." ( People v. Waidla (2000) 22 Cal.4th 690, 745746, 94 Cal.Rptr.2d 396, 996 P.2d 46 ; see also, e.g., People v. Beardslee (1991) 53 Cal.3d 68, 97, 279 Cal.Rptr. 276, 806 P.2d 1311 [a court has discretion "to determine what additional explanations are sufficient to satisfy the jury's request for information"].) In light of the deferential standard of review and the complete answers the court gave, we conclude the court did not abuse its discretion here.
