Keyframes offset and duration expression
I made two keyframes and I want to move the first keyframe to the in point of the layer above and the second keyframe to the out point of the layer above. How can I do it?

Do you want to actually move the keyframes with a script, or have the dynamic result of it, using an expression ?

Just the result with an expression

Something like this should work:
L = thisComp.layer(index-1);
t1 = L.inPoint;
t2 = L.outPoint;
t = linear(time,t1,t2,key(1).time,key(2).time);
valueAtTime(t) -
That worked perfectly!
Is it possible to change the keyframe value with an slider?

It’s easy with linear keyframes, but it can get tricky if you have custom easing that has to be preserved. Depends on what you’re doing, exactly.
