a pointer needed for constraint study

[dblhelix]

simplest basics trouble;

trying to make thom's hand stay in one place when doing a walk cycle (but i'm in chor).

tried some constraints and a null but it seems i'm not understanding something basic, since nothing achieved anything.

could someone give me the name of the null i need and say if i need to brush up on my so-called understanding of hierarchies?

 

edit, the hand should stay in one place in space regardless of the motion of the rest of the body

oh yay! got it! i could only select the the null (with the constraint picker) in the pws, wow that was too easy and embarrassing..
