control mask keyframes with slider?

[Alex Weil]

hey there,
is it possible to control the Maskpath’s keyframes via a slider.
in my case i have a mask with 2 keyframes and i want to move between them. so i made this like i would do with other stuff:

s = effect("Slider Control")("Slider");
linear(s,0,100,key(1),key(2))

its not working, and i know masks work kinda different, but i dont know how to solve this.

Try this:

s = effect("Slider Control")("Slider");
t = linear(s,0,100,key(1).time,key(2).time);
valueAtTime(t)
