unassigned keystrokes

Usually, No Op, No Action means that a keystroke that was once assigned to a plug-in or action that belonged to an extenssion is no longer assigned, because the extenssion got updated, or the action was deprecated or the plug-in could have been deleted or uninstalled from the program. Reaper saves such actions with this designation in case that extenssion or plug-in comes back.

No Op, No Action : Alt + Control + Cursor Up
No Op, No Action : Alt + Control + Cursor Down
