Which keyboard key is the HELP key on IBM i green screen

Question

I have a screen program which says "HELP - INSTRUCTIONS"

I know CMD 1 - F1 Key, CMD 8 - F8 Key and so on, but even after trying all combinations from F1 to F24 keys, I am not able to get HELP key.

Behind the scenes, I see indicator 90 (IN90) is checked, if it is ON then a HELPER program is called.

But I seem to have failed to equate IN90 on physical keyboard.

Any suggestions are appreciated.
