Zoom Player's Control Bar is a powerful and flexible interface for navigating the timeline while in fullscreen and dynamically accessing user-selected functionality.
By left-clicking the timeline area, you can instantly seek to any position in the currently playing media. By right-clicking on the left/right of the current timeline position, you can seek backward/forward a few seconds.
You can middle-click the timeline to select which text data will appear in the timeline area, control how the control bar reacts to different events and which buttons should appear on the control bar.
You can even detach the control bar and drag it onto a different monitor.
