I didn't understand what <Plug> does and how to use it. 我不明白<Plug>做了什么以及如何使用它。 I read the documentation but it is not clear to me. 我阅读了文档，但我不清楚。

<Plug> is just a special, synthetic key that is never actually sent by the keyboard; <Plug>只是一个特殊的合成键，从未实际由键盘发送; ie you cannot type it. 即你不能输入它。

With this, the :map functionality that comes from old vi can be used as an abstraction layer for plugins. 有了这个，来自旧vi的:map功能可以用作插件的抽象层。

Instead of directly mapping plugin functionality to a fixed key, plugins define a <Plug>PluginNameFunctionName mapping, which can then be freely remapped to the desired key by the user. 插件定义了<Plug>PluginNameFunctionName映射，而不是直接将插件功能映射到固定键，然后用户可以将其自由地重新映射到所需的键。 As Vim allows to check for existing mappings (via hasmapto() ), plugins can also define a default mapping if none was specified by the user. 由于Vim允许检查现有的映射（通过hasmapto() ），如果用户没有指定插件，插件也可以定义默认映射。

TL;DR TL; DR

for your own personal mappings, you can ignore <Plug> 对于您自己的个人映射，可以忽略<Plug>
if you use a plugin and need to customize its mappings, :map your own left-hand side to the <Plug> -mapping(s) provided by the plugin 如果您使用插件并需要自定义其映射，请:map您自己的左侧映射到插件提供的<Plug> --mapping（s）
if you write a plugin, enable user customization as described in :help using-<Plug> 如果您编写插件，请按照以下所述启用用户自定义:help using-<Plug>
