On mine, just ShiftHold-RCL.

I use OBJ-> a lot in class. I guess I'm one of the ones that really miss it on the Prime.

For me, it's not unusual to have multiple values that I want to work with in parallel using list processing (the two solutions to a quadratic equation, the inverse sine and its supplement, the critical numbers of a function, etc.). Often when I'm finished with the list processing, there's a particular element of the list that I want to extract to do more calculations with. It's very quick on the 50g to use OBJ-> and then arrow up to grab the one I want. (Actually, I use use PICK assigned to a key.)

I know I could store the list to a variable and then use var(<num>), but doing this interactively is far more tedious than what I can do on the 50g with OBJ-> and PICK.
