[Elecraft] new 4.22 update APF Question

[Rob @ Peg Pohorence]

Hello all, I am a new K3 user, and just did the 4.22 update. 
I am not sure how to use the APF after reading the update info.
Does the con fig menu have to be active to use the APF?
I would appreciate a step by step procedure!
thanks rob N8RT
