You can use the "Jump To" links in the drop down window under the video to skip from agenda item to agenda item. You can drag the tab on the scrollbar, directly under the video to move backward or forward in the video. It is tough to get to an exact time this way on long videos. To get to a precise point you can use the fast-forward or rewind buttons, the double arrow buttons on either side of the timeline directly below the video. Simply click once on the fast-forward or rewind button to begin, and click once again on the same button to return to the "Play" mode.
