> Prompted by your post I went looking for some, typing 'help' into the start menu search in Windows 11. An app came up called Get Help.

I just tried F1 in both Firefox and JetBrains Rider. Nothing. I wonder when that one disappeared. Though at least both have a proper online help.

edit: Trying it in all open apps, some kind of help opens in MS Teams, Discord, Outlook and Directory Opus (file manager).
