Scrubbing

The interaction of dragging a playhead across a video or audio timeline to preview content at arbitrary positions, typically with real-time visual or audio feedback. Scrubbing is ubiquitous in video editors, NLEs, DAWs, and subtitle-authoring tools. From an accessibility standpoint, scrubbing is largely inaccessible to screen reader users because it depends on a visual timeline and fine-grained mouse control. Accessible alternatives include hotkey-driven jumps by fixed increments, audio-cued timestamp announcements, and voice or conversational-agent navigation ("go to 1 minute 21").
