Toggling between term-char-mode and term-line-mode

Question

How do I bind a key sequence to toggle between term-char-mode and term-line-mode (using multi-term)?

There doesn't seem to be a term-char-minor-mode-map and a -line- that could be used for this purpose.

Answer 1

(define-key term-raw-map (kbd "H-j") 'term-line-mode)
(define-key term-mode-map (kbd "H-j") 'term-char-mode)
