[Closed] Go to next Keyframe in Trackview – possible?

I’ve been looking for this for quite a while.
Being able to go to next/previous keyframe, directly in the Trackview, simillar to those buttons found in the right bottom corner of the max, where you can go to next/previous keyframe of a currently selected object. Difference is, being in track view, object in question may not be currently selected, but they keyframes are still visible. Say, I work on X rotation curve of some object that is not even selected, so the only X rotation curve is currently visible in the trackview, using a scripted button, I move through keyframes of this current track.

I guess it might be scripted or was already scripted.

Thanks for any help.
