Request to move GTK emoji shortcut key Ctrl-period to GNOME-Shell one likes Super-period
I think the global Ctrl-* shortcut keys are not useful for general applications.
Super-period is used for the emoji shortcut key in MS-Windows and Command-period is used in Macintosh.
gnome-shell binds IBusPanelService and it can override the IBus emoji UI with the GTK one with the same shortcut key.
