What keyboard shortcuts jump to the previous/next keyframe?

The combination of j and k serves as the keyboard shortcuts to jump to the previous and next keyframe in Adobe After Effects, allowing for efficient navigation while working with keyframes in a composition. These shortcuts streamline the editing process by enabling users to quickly move between keyframes without manually scrubbing along the timeline. This is particularly useful when fine-tuning animations, adjustments, or effects associated with these keyframes, enhancing overall productivity during a project.

The other options, while including combinations of keys that may be familiar or useful in other contexts, do not serve the function of navigating keyframes.
