在Emacs组织模式中，有没有办法让内联脚注定义显示为折叠？在组织模式下，如何折叠/隐藏脚注？
这样的情况下，像这样的一行：
This effect is due to the strength of weak ties[fn:: Newman, Mark, Albert-László Barabási, and Duncan J. Watts. 2006. The Structure and Dynamics of Networks. Princeton, NJ: Princeton University Press].
可能只是看起来像这样：
This effect is due to the strength of weak ties[✭].
我还需要一个命令在必要时显示脚注。所以可能需要的是两条命令：org-hide-footnotes和org-show-footnotes。
INITIAL（2014年2月6日）：第一个工作草案。
编辑 2014年2月18日：修订功能lawlist-toggle-block-visibility以便它包含适当的if/then/else语句 - 也就是说，如果该行包含开始区域的正则表达式的必要，那么块的知名度将被切换，其他的消息说抱歉。 。 。 。为相关的代码折叠添加了引用。修改错误消息以引用一个点而不是一行。
下面也存储在Github答案的源代码：https://github.com/lawlist/lawlist-org-block-toggle/blob/master/lawlist-org-block-toggle.el
另一个相关的问题（即，完全隐藏属性抽屉包括单词:PROPERTIES:），请参考以下主题：Completely hide the :PROPERTIES: drawer in org-mode
在半相关问题上（即，创建一个自定义的块为代码折叠），也见：https://tex.stackexchange.com/a/161196/26911
此溶液用）相当最新版本的Emacs干线的（建于2014年1月19日，其中包含组织模式8.2版进行测试。 5C。因为在抽屉:PROPERTIES:通过其:END:会从脚注和HTML块分别折叠，这种解决方案设想的脚注和/或HTML代码块将不是属性抽屉内的任何地方。脚注可以在文本段落的任何地方出现，但不能有另外一对括号脚注中的 - 因为这代码查找第一结束括号，以纪念翻折区域的末端。此代码设想#+BEGIN_HTML和#+END_HTML都将是左对齐与左边距。启动视图仍然以相同的方式工作 - 例如变量org-startup-folded和org-hide-block-startup。
的org-cycle-internal-local修饰使得标签循环用于所有形式的org-模式折叠的。我们所做的只是修改了函数的分页以使其更具可读性，并添加了以下条件：((eq org-cycle-subtree-status 'subtree) (org-show-subtree) (message "ALL") (setq org-cycle-subtree-status 'all))。交互功能org-cycle仍然用于在所有各种折叠/展开视图之间循环选项卡。功能lawlist-block-org-cycle-internal-local是用于通过一个org-cycle非交互式支撑功能。这个解决方案中代码的两个部分defalias是一切正常工作所必需的。用户也可以在标题或子标题的开头直接调用交互功能：M-x org-cycle RET
要直接切换脚注或html块的可见性，我们使用交互功能lawlist-toggle-block-visibility。将光标置于任何位置上包含脚注的开始或HTML内容的开始和类型的线路：M-x lawlist-toggle-block-visibility RET

这似乎不再适用于我（和github链接已损坏）。特别是如果我在一条线上有多个脚注，它就完全失败了。你从那以后更新过吗？如果不是，我是否应该再次要求提供可见度以防其他人拥有？ – avv 2018-01-21 05:49:10
我不认为这是可能的。同样使用TAB作为其中的扩展键可能会导致密钥的更多重载。
另一方面，有没有什么特别的理由不对脚注使用脚注部分？
C-c C-x f将创建/与您有任何脚注交互。
（ORG-脚注行动&可选SPECIAL）
做脚注正确的事情。
在脚注参考中，跳转到定义。
在定义时，跳转到引用（如果它们存在），否则请给 创建它们。
如果在定义或引用时未交互创建新的脚注 。
使用前缀arg SPECIAL，在菜单中提供附加命令。
的附加命令是：
s Sort the footnote definitions by reference sequence. During editing,
Org makes no effort to sort footnote definitions into a particular
sequence. If you want them sorted, use this command, which will
also move entries according to org-footnote-section. Automatic
sorting after each insertion/deletion can be configured using the
variable org-footnote-auto-adjust.
r Renumber the simple fn:N footnotes. Automatic renumbering
after each insertion/deletion can be configured using the variable
org-footnote-auto-adjust.
S Short for first r, then s action.
n Normalize the footnotes by collecting all definitions (including
inline definitions) into a special section, and then numbering them
in sequence. The references will then also be numbers. This is
meant to be the final step before finishing a document (e.g., sending
off an email). The exporters do this automatically, and so could
something like message-send-hook.
d Delete the footnote at point, and all definitions of and references
to it.
我们可以缩小预期的结局正则表达式'] .'的东西更确定？例如，在'[fn ::'后面首次出现'] .' - 这意味着脚注内不能有第二对方括号。或者，也许我们可以说它将成为第一个''''，在一个硬回报行结尾？是否可能存在多行（例如段落或更多），段落之间有空行？未来的解决方案考虑到这个脚注将不会被放在属性抽屉里面，它会被分开折叠。 – lawlist 2014-02-06 04:14:45
脚注可能不在行尾。但脚注内不会有方括号。因此，第一次出现'''表示脚注结束。换句话说，让我们继续你的第一个建议。 – incandescentman 2014-02-06 04:21:46
