Is there a seek functionality ?

[pravin-d]

TimelineMax has a function called seek() to skip to some any animation at random

Note, that support for Superscrollorama has been suspended, as it has been superseded by ScrollMagic.
But what you're probably looking fore is a simple window.scrollTo(x, y) with x being 0 and y being your target "seek" position.
