Maxscript: how do I change the value of a key?

Question

I have an object which is pathconstrained. It has two keys, one at frame 0 and one at frame 100.

I want to change the value of the second key.

I can access it with: $.pos.controller.Path_Constraint.percent.keys[2]

But I'm not able to SET IT to a different value.

How do I change its value?

Answer 1

Setting its .value to a different one should definitely work.
