How can I find out what that shortcut key does?
推荐答案
有两个潜在的信息来源.首先，如果是内置快捷方式，通常在帮助文档中.例如，如果你执行 :help CTRL-I，它会带你到一个关于在你的跳转列表中移动的帮助条目.
There are two potential sources for information. First of all, if it's a built in shortcut, it is normally in the help documentation. For instance, if you do :help CTRL-I, it'll take you to a help entry about moving around your jump list.
但是，您有可能从您的 .vimrc 文件之一或文档不足的插件中获得自定义映射.在这种情况下，尝试使用 :map 它将列出当前活动的所有自定义键盘映射.这将为您提供三列:
It is possible, however, that you have a custom mapping from one of your .vimrc files or an underdocumented plugin. In that case, try using :map which will list all custom keyboard mappings that are currently active. That will give you three columns:
- 映射适用的模式
- 键盘快捷键
- 运行的命令
然后您可以使用 :help 进一步调查运行的命令.
You can then use :help to further investigate the command that is run.
