Comment 65 for bug 1218322

(1)
I found that in dconf-editor
-> desktop -> ibus -> general -> hotkey
both next-engine & next-engine-in-menu are set by default to 'Alt+Shift_L'
I do not know whether this is related or not.

Switching the language indicator (using the mouse) to my other language (Hebrew) allows me to switch between hebrew and english using Alt+Shift (defined in dconf: org -> gnome -> desktop - > input-sources -> xkb-options ['grp:alt_shift_toggle']
Unfortunately, I have to do this for each window separately, that is, if the indicator shows "En", I will not be able to switch language using the Alt+Shift.

I agree with the previous post - I do not see the point in this change from previous behaviour. The system is less usable than before (unless I am missing something). I wish to have simple way to choose the shortkey for language switching and that the indicator would follow.
