They also usually assume a lot about the users’ knowledge of the domain of the program itself.

In my experience, many programs’ man/help is very brief, often a sentence or less per command/flag, with 2 or more terms that don’t mean anything to the uninitiated. Also, even when I think I know all the words, the descriptions are not nearly precise enough to confidently infer what exactly the program is going to do.
Disclaimers for potentially dangerous/irreversible actions are also often lacking.

Which is why I almost always look for an article that explains a command using examples, instead of trying to divine what the manual authors had in mind.

win + space to switch between keyboard languages
win + tab to open the desktop switcher
win + ctrl + t (if you have PowerToys installed) to prevent other apps from stealing focus from your window

I use the tiles to “pin” programs that I use semi-regularly and can’t be bothered remembering the name of. Or that share an inconveniently long prefix with the name of another program. Or that I have multiple versions of installed, with a specific version I usually need.

I don’t like pinning such programs to the task bar because they add unnecessary clutter while not in use.
