Install the Flash Player for Your Browser
The Hello Linux! Video Tutorials can be viewed in any Linux or Windows web browser that has had the Flash Player installed. Many browsers already have the Flash Player installed. If you are uncertain, select a sample Video Tutorial from the previous web page and see if it appears on your screen and plays. If not, the Flash Player is available free of charge at www.adobe.com. Do the steps to download and install the appropriate version for your operating system. The steps for installing the Flash Player are shown at this web site.
How to Use the Hello Linux! Video Tutorial Controls
There are control buttons and a scroll bar at the bottom of the video display.  The buttons at left allow you to Start, Pause and Stop a Tutorial.  Remember that you can pause a Tutorial at any time to get a longer look at all of the information on the screen, such as to read some text in the output of a command.   The scroll bar across the bottom has buttons on the left and right.  By clicking on a location in the scroll bar, the video will advance to the location that you clicked on.  For example, if you click at a point three quarters of the way along the scroll bar, you will advance to three quarters of the way through the Tutorial.  The buttons at the right allow you to "jump" forward and backward in the video.  Enjoy the Video Tutorials!
