I continue my presentation so  yeah ,
channel selection is um very important , very often used. Volume is not often used but people uh want to have control on volume and that makes sense of course. And n then you have things which are very much less often used like the settings. Audio settings , screen settings , even teletext and channel settings. All of them. they're not often used and they are s more or less relevant. It seems that people find teletext teletext uh relevant , even if I personally never use it but seems that it's average relevant at least , so.
