Emacs: set key that is local to java mode.

Question

I am inspired by this url .

It suggests setting a global key (global-set-key (kbd "RET") 'newline-and-indent) .

However, I would like to set RET to 'newline-and-indent ONLY in the Java mode. What code should I add to the init.el in order to achieve this ?

Answer 1

You need to apply it to the mode specific keymap. Something like the below should work.

(defun on-java-loaded ()
  (define-key java-mode-map (kbd "RET") 'newline-and-indent))

(add-hook 'java-mode-hook 'on-java-loaded)
