◆ Find()

URSequencePoint * AzToolsFramework::UndoSystem::UndoStack::Find ( URCommandID  id,
const AZ::Uuid &  typeOfCommand 
)

Usage: return the first command in all active command trees with a matching id returns NULL on failure to make any match

◆ Slice()

void AzToolsFramework::UndoSystem::UndoStack::Slice ( )

Usage: slices off all commands above the current cursor example: undo followed by new commands should slice to remove redo commands no longer viable
