如何使用Cx 8前缀设置密钥？

Question

假设我想重新绑定C-x 8 x到?。所以我做：

(global-set-key (kbd "C-x 8 x") (lambda () (interactive) (insert "?")))

但它不起作用：它仍会插入默认的x符号。然后我都尝试了：

(global-unset-key (kbd "C-x 8 x"))
(global-set-key (kbd "C-x 8 x") nil)

没有效果。

这是我现在用于希腊人的内容：

Answer 1

您必须在中设置密钥iso-transl-ctl-x-8-map。如：

(eval-after-load 'iso-transl
  '(define-key iso-transl-ctl-x-8-map "x" "?"))

这是因为C-x 8实际上是在中定义的key-translation-map，它会覆盖全局地图。
