If you’re old time desktop user you wouldn’t have to look for these keys, they’re at the same place for decades. Heck, I even don’t know which combination I’m pressing to go to the begining of page or line, that’s muscle memory at this point.

That said, I acknowledge that you have your own prefered way, and that’s how it should be. As it also should be that these extra keys exist at least on bigger laptops, if not on ultraportables.
