SnapScrubber is an animation utility that snaps the timeline scrubber to the nearest keyframe in the scrub direction. By holding down the ALT key while scrubbing with the mouse, users can reliably land exactly on existing keyframes without relying on keyboard navigation. This behavior prevents the accidental creation of unwanted keyframes when working with the autokey feature during pose blocking or animation adjustments. The default modifier key can be customized by editing the provided Python script.
