In my fresh install of Kubuntu 14.04, I can't use anymore the (pretty useful) shortcut to move along words: (right) CTRL + Left (or Right) Arrow.
The Left-Control key is working fine. If I try to add a secondary shortcut for this action in System settings > shortcuts & gestures > standard shortcuts > forward one word, I got an error popup saying:
This key is not supported by Qt
My keyboard didn't change, it's a basic French AZERTY 101 keys. Is there a trick to configure something somewhere?
