Which brings me to another point. There is at least one such
correspondence that Emacs
users are supposed to know about, that I think is unnecessary, and
that is C-j = LF = \n.
That is used for example in I-search and in arguments to query-replace etc.

I would like some alternative way to enter newline in arguments,
something having to
do with <return> since that's the key actually associated with "new
line" for all
those you don't know their ASCII.

That key should be used in I-search with the same meaning as C-j has
now, and should
be possible to use instead of C-q C-j to enter a newline in minibuffer
input. Maybe
<C-return> could be used for this?

Then this would be an alternative just for people with window systems,
but I think people
who would benefit from this almost always have a window system anyway.
