将密钥设置为不执行任何操作的最佳方法

那就是 ignore 功能:

ignore is an interactive compiled Lisp function in ‘subr.el’.

It is bound to <mouse-movement>, <bottom-divider> <mouse-1>,
<right-divider> <mouse-1>.

(ignore &rest IGNORE)

Do nothing and return nil.
This function accepts any number of arguments, but ignores them.

如果它足够好 mouse-movement 事件中,触摸板应足够好:

(global-set-key [mouse-12] 'ignore)
