Turning on all Quick Keys in a system (Sentinel)

Has anyone found a way to select (turn on) all the quick keys in a system in Sentinel without stepping through all 100 of them and turning them on?



I see that when importing a system from the database, they are all on by default, but when building a system, they are all off.



I tried CTL-A to select them all, but that was ignored. There's gotta be a better way!
