Even though you've been using Emacs for a long time, you usually use arrow keys, you shouldn't edit the file.

Stupid people who always use arrow keys to control cursors are not entitled to edit the file. (I was inspired by this article.)

(global-set-key [up] 'kill-emacs)
(global-set-key [down] 'kill-emacs)
(global-set-key [left] 'kill-emacs)
(global-set-key [right] 'kill-emacs)

Behavior	Key Binding	How to remember
Move Cursor 1 Line Up	C-p	preverious
Move Cursor 1 Line Down	C-n	next
Move Cursor 1 Character to Left	C-b	backward
Move Cursor 1 Character to Right	C-f	forward

Note: This is a joke. Unlike save-buffers-kill-terminal, which is assigned to C-x C-c, kill-emacs forces Emacs to drop without warning even if it has not been saved. I will not be responsible for the loss of important edited data if automatic backup is turned off.
