Emacs keystrokes don't work in the textarea I'm using to write this comment in Google Chrome.

Specifically none of these do anything like what they do in Emacs: C-a, C-e, C-n, C-p, C-f and C-b.

This is on Linux, but ISTR finding the same state of affairs on MacOS many years ago during some previous iteration of this conversation.

They also don't work in VSCode.
