Comment 10 for bug 1242572

Gnome3, Unity, Mac OS X and Windows default to using "Super+Space" (aka win+space,logo+space, etc) combination to switch keyboard layouts.

I've tried to get "Super+Space" key to work with xkeyboard-config and it doesn't appear to work. (Such that the key-combination to change layouts is consistent everywhere)

xkeyboard-config manpage only offers:
grp:alt_space_toggle Alt+Space
grp:lwin_toggle Left Win
grp:rwin_toggle Right Win

But ideally it is desired to also offer following options:
grp:lwin_space_toggle Left Win + Space
grp:rwin_space_toggle Right Win + Space

Bruteforcing / setting above by chance did not work =)

Can those two options be added?
