Enable Scroll Lock / Num Lock on extended keyboard?

[rickrob]

I have the original extended keyboard for my Mac IIx.

All the keys are good, but I can't figure out how to turn on the Num Lock or Scroll Lock and get the light to come on...

I've tried a bunch of combinations with the shift, option and command keys.

The LED's a good.  What are the key combinations to get those lights to come on?

Edit: Ha. 2 seconds after posting this I figure it out.  Shift->option
