can someone please describe the right forearm pickup in some detail? thanks

The Right Forearm Pick Up, the Right Arm Vertical Take-Away, the Right Forearm Take-UP. It's lnown by many names.

It is a non-left shoulder take-away.

The movement of the right arm is up, back and in- simultaneously and immediately. Up, Back and In is a three dimensional motion on plane. Much like the motion of yanking a cord of a small engine to start it up.
Take the right arm up like being "sworn in" in a court room. It is a simply move that evades us in words.
Check a search for the word Fanning on this site, too.

In Homer Kelley’s own words about the Right Arm Vertical Take-Away “..be sure that you have it. It is absolutely essential to alignment golf. If you have a shoulder turn takeaway you immediately have gone into pivot control hands."
