修改 org-mode 的省略符号

org-mode 默认使用三个点 (...)来只待隐藏内容。不过我们可以通过修改 org-ellipsis 的值来修改这个表示方式

org-ellipsis is a variable defined in ‘org.el’.
Its value is nil 

  This variable is safe as a file local variable if its value
  satisfies the predicate which is a byte-compiled expression.

Documentation:
The ellipsis to use in the Org mode outline.

When nil, just use the standard three dots.  When a non-empty string,
use that string instead.

The change affects only Org mode (which will then use its own display table).
Changing this requires executing ‘M-x org-mode’ in a buffer to become
effective.

You can customize this variable.

比如我比较喜欢使用 ⤵ 来指待隐藏内容。

(setq org-ellipsis "⤵")

最后的效果如下图所示:
