I've upgraded my fedora 17 to 18 using fedup. I've installed two language and when I want to switch from one two another using Alt+Shift (Like in my Fedora 17), I'm unable. I followed System Setting>Hardware>keyboard>layout setting>Short-cut Setting. Then I clicked on Switch to next source" to determine new short-cut. When I click on this, it "disabled" turns to "New accelerator" and waiting for my short-cut. I define Alt+Shift, but it can't recognize my entries. My Alt and shift buttons work fine in other place in Fedora.
Would you please help me how to solve my problem ?
