8.1. 输入音标与特殊符号

在电子文档中输入音标符号（及其其它特殊符号）从来都很麻烦。

macOS 上有一个收费软件，Alfred，可以用来定义很多快捷流程（workflow）去完成相对复杂的任务。

Alfred 的使用方法，参见： https://github.com/xiaolai/apple-computer-literacy/blob/main/alfred.md

我用 Alfred 作为辅助在电脑上输入各种特殊符号。以下是 Alfred workflow 文件：

IPA-Phonetic-Symbols.alfredworkflow

以启动关键字 ipae 为例 —— 呼出 Alfred：

这时，就可以用 CMD + 数字 的方式，将对应的符号插入当前文本。比如，CMD + 4 就是将 <span class="pho">ɝː</span> 插入当前文本编辑器。

以下罗列的是各个符号对应的 Alfred 关键字（Keywords）：
