Fedora Workstation 31 GNOME
My installation has a default of English (UK) but occasionally I use Japanese so I installed Japanese language support. When using the Japanese IME one of the keyboard shortcuts is Alt+`. However, when I use this it brings up an application switch screen.
I looked through the Settings -> Devices -> Keyboard Shortcuts but there is nothing defined for Alt+`. I also noticed that "Switch Application" is set to Super+Tab (which works) but Alt+Tab does the same thing even though this is not defined anywhere.
So my question is, how can I disable these unwanted keyboard shortcuts?
From your description, it sounds like an application is grabbing these keys, and that the application is Gnome itself. I don't use Gnome, but I have seen here people recommending 'Gnome tweak tool' as a way to change Gnome options. It might also be possible to change this in the application itself to something else, say Ctrl+ or WinMenu+. There is a small chance that this is Wayland; I can't advise how to fix that as I am unfamiliar with it, but a search should turn up options.
The above assumes that the keys aren't hard coded into the application; that shouldn't be the case these days, but if it is, you would have to download the src.rpm, unpack it using rpmbuild, create a patch to override the encoded default, rebuild the binary rpm, and install it. To prevent it from being replaced on update, you would then have to block updates in /etc/dnf/dnf.conf. Major hassle.
