Hello.
Here's a website I use for watching documentaries https://topdocumentaryfilms.com/
Once you search for or find a documentary you want to listen to, press enter on the play graphic and the video will start, youtube shortcuts like K for play/pause, j/l/left/right for forward/backward, 1 to 9, skips you through the documentary, m for mute, up/down to raise and lower the volume.
