And who gets to be the judge of which keybinds are "random and mysterious"? Every single OS has it's own different keybinds you need to learn if you want to be eficient with. MacOS has different. KDE has different. Gnome has different. Windows has different. It's not their fault you don't know them or haven't bothered to look into them for the OS you daily drive at home or at work and remain "random and mysterious" to you. Every switch to a new OS involves a certain learning curve for any user.

It's called basic computer literacy in my country and it's also must have knowledge for most white collar jobs as it's part of the curriculum out of high-school.

If you don't have the basic skills to Google "hotkey keyboard layout switch Windows" or something along those lines for your OS, then "you'd better get used to asking people if they want fries with their order", as our instructor used to say, since you're not getting into any tech career if you can't google basic stuff.

> that nobody asked for

As a multilingual person who has to type in 3 languages on daily basis, the keybinds to quickly switch languages are defiantly something I would have asked for and I'm glad they exist.
