Scrcpy shortcuts break Android's own keyboard shortcuts on MacOS

[youbzh]

Please read the prerequisites to run scrcpy.

Also read the FAQ and check if your issue already exists.

Environment

• OS: macOS Sequoia
• Scrcpy version: 3.3.4
• Installation method: brew
• Device model: Boox Tab Ultra C Pro
• Android version: 13

Describe the bug

When using:

scrcpy --no-video --no-audio --keyboard=uhid --mouse=uhid

The native Android keyboard shortcuts (for instance meta + B for opening the web browser) don't work.

Then when using:

scrcpy --no-video --no-audio --shortcut-mod=rsuper --keyboard=uhid --mouse=uhid

The above keyboard shortcuts work, BUT then copy-pasting using the left CMD key is broken.
I've tried fixing this with various workarounds, for instance, adding my own copy/paste shortcut on Android using Key Mapper, but this works only for pasting from host to device, no the other way around.

Maybe I'm missing something.

Thanks for your help and the great app.

The above keyboard shortcuts work, BUT then copy-pasting using the left CMD key is broken.

I understand, but unfortunately this is the expected result.

Here is what happens.

By default, LAlt and LSuper are used as shortcut modifier.
So when you press LSuper+B, it it handled as a scrcpy shortcut.
And when you press LSuper+C, it is also handled as a scrcpy shortcut, which triggers COPY.

When you change the shortcut mods to free LSuper, then LSuper is forwarded to the device, and the shortcut is handled by Android directly. That's why LSuper+B is correctly handled.
But on Android, there is no such thing as LSuper+C to trigger a copy. It's LCtrl+C.

Thank you very much for clarifying this. How about adding an argument to disable scrcpy shortcuts? Would that be possible? (This is then a feature request, not a bug ^^).

How about adding an argument to disable scrcpy shortcuts?

When you run scrcpy --shortcut-mod=rsuper, you're basically disabling shortcuts for the other keys.

The problem is that in your case, you need scrcpy shortcuts if you want LSuper+C to copy.

Oh okay, I think I understand things better now.

By default, LAlt and LSuper are used as shortcut modifier.
I guess you meant LCtrl (for windows/linux) and LSuper (for macOS)?

Then the copy/pasting that's triggered by scrcpy is a special copy/paste that not only copies the text but forwards it to the host/guest machine at the same time? I'm asking because my workaround above (adding LSuper+C/V as a copy/paste shortcut on Android) works in the Android machine but I can't paste text back to the host machine.

So in my case I guess I'd need only a few scrcpy to be active and others to be inactive. Then the other workaround is to maps Android shortcuts to keys that aren't used by scrcpy, which I'll end up doing.

Thank you again, scrcpy is really an amazing piece of software ☺️
