To delete an keyframe, click any keyframe under the Animation Timeline to select it, then click on the Delete Keyframe button to delete your keyframe from the timeline. Please note, that you can't delete the 0% or 100% keyframes, as these are default keyframes required for your animation timeline.
After you delete any keyframe, the 0% keyframe will automatically be re-selected as the active keyframe to edit.
