lapce swallowed the xlib send_event ControlMask while sublime won't

[diyism]

I've used myboard.py to realize debian system-wide VIM keyboard shortcuts(https://github.com/diyism/MyBoard/blob/master/myboard.py) for over 11 years,
it's very convenient, it works well with the sublime editor.

For example, when I type only "z" key in sublime,
the system-wide running myboard.py will grab the "z" and do send_event('z', X.ControlMask, 1) with python xlib,
and the sublime editor can receive the "ctrl+z" combination and execute the undo command.

But this won't work in lapce, the lapce only received the "z" character.

Is there any possibility to realize the same effect with the sublime?

Thanks.

Is myboard sending a real key events or doing something weird?

@panekj I'm not expert, I've asked gpt4:

Perhaps what Lapce swallowed was the first manually entered 'z' key event, not the simulated Ctrl+Z combination event that I talked about in my first reply.
