In Cinnamon, when I open Region & Language settings and click Options, it says both the "Switch to previous source" and "Switch to next source" keyboard shortcuts are set to Shift-Ctrl-Space. I'm not sure how two different shortcuts can be set to the same thing, and indeed, when I type Shift-Ctrl-Space nothing happens. It also says, "You can change these shortcuts in the keyboard settings," but when I look in the keyboard settings, there are no shortcuts to be set there for switching among input sources.
Cinnamon doesn't use the new keybindings in gnome Region & Language settings. Cinnamon uses Alt-Shift to switch input source. It can be changed, here's a list of valid key combos $ gsettings range org.gnome.settings-daemon.peripherals.keyboard input-sources-switcher enum 'off' 'shift-l' 'alt-l' 'ctrl-l' 'shift-r' 'alt-r' 'ctrl-r' 'alt-shift-l' 'alt-shift-r' 'ctrl-shift-l' 'ctrl-shift-r' 'shift-l-shift-r' 'alt-l-alt-r' 'ctrl-l-ctrl-r' 'alt-shift' 'ctrl-shift' 'alt-ctrl' 'caps' 'shift-caps' 'alt-caps' 'ctrl-caps' To set gsettings set org.gnome.settings-daemon.peripherals.keyboard input-sources-switcher 'alt-shift' Then logout for the change to take affect.
Isn't it a bug that the Region & Language settings dialog told me to change the binding somewhere where I can't actually change it? Isn't it a bug that there is no GUI for changing this binding?

Following arguments do not work: 'ctrl-shift' 'ctrl-shift-l' 'ctrl-shift-r' Other arguments like 'caps' 'shift-caps' are ok.
