You can change the speed of the Youtube video too. Go to Settings, then Playback speed. Speed ranges from 1/4 to 1 1/2.Being a US veteran, allowed obtaining a legal copy of SW 2020 for USA $100, well worth it! Used to be $20, but oh well.
As for learning to use it, any & every time I want to do something new, I simply google the description of the new topic and find multiple youtube videos on that topic. One caution though, watch all of them, some of the presenters have a bit of a problem communicating clearly, as well as some speed through the demonstration, which of course can be handled by stopping and going back over the recording.
