How to assign control n to bind any readline function

Question

Tried to assign control n to bind any readline function in bash but can't, e.g:

bind '"\C-n" : previous-history'

but still work as bind -x '"\C-n" : "echo foo"'

Why and how to solve it?

Try bind '"\C-n": previous-history', without no space before :. This is not an answer because I cannot answer "why?". — Kamil Maciorowski, Commented Sep 15, 2020 at 6:20

As Kamil Maciorowski said Try bind '"\C-n": previous-history'

without any space before :

While it's fine to have space after :
