大致的答案如下。根据gschema.xml包含默认 GSettings 定义的文件内容，它们定义在：
$ gsettings list-recursively | egrep "Alt|Shift|Super|Space|Win|Meta|Primary|Control|Ctrl|Tab" | grep org.gnome | awk '{print $1}' | sort -u
org.gnome.Charmap.WindowState
org.gnome.desktop.wm.keybindings
org.gnome.desktop.wm.preferences
org.gnome.metacity.keybindings
org.gnome.mutter
org.gnome.mutter.keybindings
org.gnome.mutter.wayland.keybindings
org.gnome.settings-daemon.plugins.media-keys
默认值如下：
$ gsettings list-recursively | egrep "Alt|Shift|Super|Space|Win|Meta|Primary|Control|Ctrl|Tab" | grep org.gnome
org.gnome.settings-daemon.plugins.media-keys logout '<Control><Alt>Delete'
