@daniel.schaaaf and @VaZso: I think we already discussed that elsewhere, right? I have not found any switch to enable or disable sticky shift. Interestingly, I found that the feature does not work in all apps: On my setup, "typical" smartphone apps like messengers and firefox tend to have it enabled, while more advanced things like terminal emulators and text editors usually don't. Seems like apps can choose to support that accessibility feature or not.
