because NWC doesn't exclude grace notes when auditing stems, an option to find grace notes would be useful
I think the Find syntax has changed, but this will locate your grace notes:
Create a grace note at the beginning of a staff |Note|Dur:8th,Grace|Pos:0o|Color:0|Visibility:Default, copy it to Find, and edit it, changing the variable elements to wild cards: |Note|Dur:*,Grace*.
