TUTORIAL.he is slightly special, in that both an editor and a
reader[^1] use the same mode (because once in a while the user is
instructed to edit some part of their copy). In most other cases, I
prefer remaps turned on when I’m an editor or reviewer, and off when
I’m a reader.

Most people, when in the reader role, probably won’t and shouldn’t have to.
If I’m editing a text in a bidi language, though, I am expected to use
format control characters, and so I must know where they are or are
not. In the same vein, when I edit a program expected to conform to a
coding style, I must know where spaces and tabs are, so I do not
introduce whitespace-only changes or trailing blanks and keep
indentation consistent. Or when I edit anything that will end up as a
web page I want to know which spaces and hyphens are non-breaking, so
the page will wrap correctly no matter how the user resizes their
window and/or zooms the page. (No, I do not trust tools to do these
things right; if they could, we would not need format control
characters at all. I like tools to let me check what they did and
correct if necessary.)
