在 macOS 上的终端中运行的 Vim 中，Ctrl+6 不会编辑备用缓冲区

Question

在 macOS High Sierra 10.13.6 上，我vim在终端中启动并在 Vim 中输入以下命令。

:e foo.txt
:e bar.txt

现在，如果我按Ctrl+ 6，它不会返回到备用文件foo.txt。

Ctrl+ Shift+6工作正常并且确实返回到备用文件foo.txt。

Ctrl我使用过的所有其他 Vim、MacVim 或 GVim 都会在按+时返回到备用文件6。为什么它不能与vimmacOS 一起使用？

这是我的 vim 版本详细信息：

/usr/bin/vim

根据帮助，这是预期的行为：

In a terminal CTRL-^ needs to be entered as Shift-Control-6.  CTRL-@ as
Shift-Control-2.
