Skip forward and back in a media file
Skip Forward and Skip Back are located under the Media menu. Use them to skip forward/back in the track by 5 seconds. These functions also have shortcuts so it is possible to control them from the keyboard.
The Media Controls dock displays the present position along the track as a slider, with the position and duration on either end in HH:MM:SS format. Move the slider by clicking or dragging to skip to the time on the track. (This becomes less accurate if the file has a long duration).
