Emacs gtk key theme is pretty useful to add some common shortcuts to the gtk entries. Basically setting ‘gtk-key-theme’ to ‘Emacs’ using gsettings works great for most of the gtk applications.
Only exception is the gnome-shell. Gnome shell entries do not obey gtk-key-theme setting. It is pretty annoying to lose ability to use Ctrl-h or similar emacs conveniences when focusing an entry on gnome-shell, for example after switching to overview, or using Alt+F1.
I wanted to check for gnome-shell to see whether I can add gtk-keys.css, but along the lines of gtk source code, I saw some commits stating ‘key themes are not used anymore’ like this https://github.com/GNOME/gtk/commit/f2e197a389cc9d1f44858ec8e11d9996f6766faa
So I am wondering whether gtk-key-themes is retiring or gnome-shell has a bug not obeying gtk-key-themes. And If gtk-key-themes is retiring what is the successor?
