Though it might not be ideal for this use case, you could use the TestStand "Find" feature (Ctrl+F) and then double-click on the found item to go to it.
Yes the find feature will work when not running, I guess I was thinking it would be useful in the "variables" tab during runtime, so that I could search the runstate tree also, which isn't populated until runtime.
It does work in the variables tab during runtime. At a breakpoint in your execution, do "Ctrl+F" and you can then search the variables view of the execution. You must be at a breakpoint, but this really only makes sense at a breakpoint anyway.
