Using the space bar will pause and play a video that is in full-screen mode. You can also enter and exit the full-screen mode by simply hitting the "F" key. These two shortcuts are comfortable, and if you work with them, you will see how much better they are than searching for the full-screen icon with your mouse. To follow these, you may use the number above the letters on your keyboard.
If you’re watching a video, you can press a number to move to a part of the video, and each number correlates with a ten percent adjustment. For example, if you are perusing the video, you can hit the "one," and it will jump to a ten percent spot of the video. Similarly, pushing the “nine” will take you to the ninety percent spot of the video.
