Emacs 输入}后如何将点切换到上一行？

我正在使用带有cc模式的emacs24，我想知道如何使我的emacs更“聪明”。键入a}后，它将自动插入新行并按例外情况缩进。我想知道如何将该点切换到上一行。 例如，当我定义一个函数时，现在我的emacs行为是：

void f()
{
}
//point

“//点”是输入}后光标的位置。 但我想要的是：

void f()
{
    //point
}

我希望光标的位置可以切换到上一行并自动缩进。

我知道emacs可以做到这一点，但我不知道怎么做，谁能帮我？

我想你在追求这些<代码>C-M-u，

C-M-d

，

C-M-f

和

C-M-b

练习一下。。。它们是全球性的，几乎在所有模式下都会表现出情境性

更新：

哦。。您似乎希望自动放置光标。。实际上，在更一般的情况下，Emacs将帮助您根本不键入

}

。我的意思是emacs可以自动插入关闭参数

有一个内置的 电对模式

我不相信任何电子产品，所以我编写了这个函数

(defconst insert-logical-brackets-logical-bracket-begin "{")
(defconst insert-logical-brackets-logical-bracket-end "}")
(defconst insert-logical-brackets-default-style 0)
(make-variable-buffer-local 'logical-bracket-begin)
(make-variable-buffer-local 'logical-bracket-end)
(make-variable-buffer-local 'insert-logical-brackets-default-style)
(defun insert-logical-brackets(&optional style)
  "If STYLE = 0(default, according to `insert-logical-brackets-default-style' value), make a newline before opening bracket, if line is not empty. Make a newline after closing bracket, if there is something after this bracket. Make two newlines in the middle.
If STYLE = 1, don't make newlines before opening a bracket(one of c styles).
If STYLE = 2, don't make newlines before opening and after closing bracket.
If STYLE = 3, allways make all newlines.
If STYLE is not nil, don't make newlines between brackets(still makes before/after lines)."
  (interactive "P")
  (when (eq style nil)
    (setq style insert-logical-brackets-default-style))
