outline-mode

首先，在*scratch* buffer中键入下面一段文字：

     * Food
     This is the body,
     which says something about the topic of food.

     ** Delicious Food
     This is the body of the second-level header.

     ** Distasteful Food
     This could have
     a body too, with
     several lines.

     *** Dormitory Food

     * Shelter
     Another first-level topic with its header line.

然后将该buffer的模式转为outline-mode:

(defun myfunc ())


import java.util.*

public static void main(String test){
    try{
}
}

下面我们来实验一些操作，但在这个之前需要解释一些概念：

概念

大纲模式将buffer中的行区别为：

正文（Body）：除标题行外的其他行
标题（Heading）：以一个或者若干星号加一个空格开始的行

注意：可以定制变量outline-regexp来识别标题行

标题和正文行的组合：

记录（Entry）：标题和其下所有的正文行组成一个记录或者条目
子树（Subtree）：标题和其下的所有子标题以及它们的正文行组成一棵子树

注意：
1. 记录的直接正文只能在记录的开始部份
2. 如果记录的正文或者正文和所有子树被隐藏，则该标题行的末尾会出现省略号(...)
3. 如果记录仅仅子树被隐藏，那么在记录正文后面会出现省略号(...), 如果该记录没有正文，则效果同上

快捷键

outline-mode使用如下快捷键和命令：

移动命令：

Key Binding	Function	Comments
C-c C-n	outline-next-visible-heading	move by visible headings
C-c C-p	outline-previous-visible-heading
C-c C-f	outline-forward-same-level	similar but skip subheadings
C-c C-b	outline-backward-same-level
C-c C-u	outline-up-heading	move from subheading to heading

全局隐藏：

Key Binding	Function	Comments
C-c C-t	hide-body	make all text invisible (not headings). Recursively, Body
C-c C-a	show-body	make everything in buffer visible. Recursively, Body
C-c C-q	hide-sublevels	make only the first N levels of headers visible.(C-u, M-(number) to pass the level n, Recursively, Heading
C-c C-o	hide-other	show current entry, and all level parent headings， hide

位置相关的隐藏

(如果是在标题行，则指当前标题，否则是指正文行所属的直接上级标题, 影响局限于该标题下的子树）

Key Binding	Function	Comments
C-c C-d	hide-subtree	Recursively, Subtree(Body, Heading)
C-c C-s	show-subtree	Recursively, Subtree(Body, Heading)
C-c TAB	show-children	Direct, Heading
C-c C-k	show-branches	Recursively, Heading
C-c C-l	hide-leaves	Recursively, Body
C-c C-c	hide-entry	Direct, Body
C-c C-e	show-entry	Direct, Body

The remaining commands are used when point is on a heading line. They apply to some of the body or subheadings of that heading. C-c C-d hide-subtree make body and subheadings invisible. C-c C-s show-subtree make body and subheadings visible. C-c TAB show-children make direct subheadings visible.

No effect on body, or subheadings 2 or more levels down. With arg N, affects subheadings N levels down. C-c C-c make immediately following body invisible. C-c C-e make it visible. C-c C-l make body under heading and under its subheadings invisible. The subheadings remain visible. C-c C-k make all subheadings at all levels visible.
