如何强制蓝牙键盘连接进入 Windows 模式？

许多混合（PC/Mac 或 Windows/MacOS）蓝牙键盘都有一个物理按钮（Keychron）或热键（Logitech）可以在 Windows 和 MacOS 模式之间切换。

这Seenda 无线背光蓝牙键盘 ISJ-WJK70BT4没有这样的硬按钮或软按钮。它会自动检测 Windows 和 MacOS，并相应地更改按钮布局，最著名的是交换Win/Option和Alt/Cmd。

我不知道 Seenda 蓝牙键盘是如何进行这种检测的，但是当连接到 Ubuntu 时，键盘将切换到 MacOS 模式。毫无疑问。

如何让键盘认为蓝牙连接源自 Windows 计算机而不是 Mac 计算机？

无论是极其简短的手册还是客户服务都不知道有任何隐藏的组合键可以强制进入某种模式。

Seenda ISJ-WJK70BT4 键盘内置有手动重新识别系统的选项。为此，您可以按Fn + Left Shift + W。我在 Arch Linux 上遇到了同样的问题，我用这种方法解决了它。
