Hello.
Is there such a feature as in Emacs. Meta-JAlt-J ?
At one time I had it swapped because of a different keyboard.
Is there such a  feature as Alt-J though?

I should have been more explicit. What I should have said instead but I didn’t, was a counterpart to Emacs Alt-J on the prompt line minibuffer.
The only results after searching Google and not the documentation was redirecting to Newline characters used as-is in the prompt · Issue #1865 · mawww/kakoune · GitHub
but this is not what I’m referring to.

Since in the minibuffer submits the argument, you can’t use it to insert a newline. You can do that with C-q C-j, which inserts a C-j control character, which is formally equivalent to a newline character (see Inserting Text). Alternatively, you can use the C-o (
open-line) command (see Blank Lines).
