I've noticed that the Ctrl, Shift, and Alt keys fail to work properly when Xdmx fails.

我注意到在Xdmx失败时，Ctrl、Shift和alt键无法正常工作。

There isn't much to handling the pressing of control keys (Shift, Alt, and Ctrl). You need to ignore these keyboard events by doing the following.

对于控制键(Shift、Alt和Ctrl)的按键事件并不需要过多的处理。

youdao

A character or function key can be pressed in combination with one or more ALT, CTRL, or SHIFT modifier keys.

按下字符或功能键的同时可以按下alt、Ctrl或Shift修改键中的一个或多个。

But you can also remap other key functions such as Ctrl, Shift, Alt, various click and scroll mouse functions, and also launch other game profiles and third party programs.
