zsh in multi-term

Question

I run zsh in multi-term. M-p and M-n allow me to jump through the input history.

Is there a way to make M-p and M-n behave like up-line-or-beginning-search and down-line-or-beginning-search (jumping only through entries which start with the already input characters)?

Answer 1

Try:

(with-eval-after-load "term"
  (defun term-send-M-p ()
    "Type M-p in `term-mode'."
    (interactive)
    (term-send-raw-string "\ep"))

  (defun term-send-M-n ()
    "Type M-n in `term-mode'."
    (interactive)
    (term-send-raw-string "\en"))

  (define-key term-raw-map (kbd "M-p") #'term-send-M-p)
  (define-key term-raw-map (kbd "M-n") #'term-send-M-n))

I think multi-term binds M-p and M-n to term-send-up and term-send-down by default, which tries to do the same as pressing the arrows in a terminal. IIRC, multi-term has an elaborate binding override mechanism, which you may have to use instead of plain define-key.
