Which method allows you to show video keyframes in the Timeline panel?

Zooming in on the timeline is indeed the correct method to display video keyframes in the Timeline panel. When working with video clips in Premiere Pro, keyframes are essential for creating animations and effects over time. If the timeline view is too zoomed out, the detail necessary to view keyframes may not be visible. By zooming in, users can see these keyframes more clearly, allowing for precise editing and adjustment of animation properties.

Other methods might not provide a way to visualize those keyframes effectively. Expanding the audio track does not pertain to video keyframes, and while right-clicking for keyframe options might be useful for certain tasks, it isn't specifically for displaying them. Pressing the K key could be a shortcut for cycling through certain functions related to keyframes, but it does not serve the purpose of revealing them on the timeline directly.
