@ Aliaksandr
Please stop writing such phrases.
The bug is almost fixed in Ubuntu 14.04 in all sessions.

If you have concrete problems - write here about them, not holy war emotions.
Also you can quietly test your exotic <Right Control> layout switcher in other distros. You can help Ubuntu community to fix this bug too.

>     * Pressing keyboard shortcut to switch keyboard layout causes temporary loss of focus (bug 1244090)
>     * Unity shortcuts (Super+A/F/M/C/V) do not work on non-latin layout in Trusty - shortcuts are defined via keyboard layout, not the keys (bug 1280759)
>     * Binding ctrl+shift, alt+shift, etc for switching keyboard layout makes shortcuts with ctrl+shift, etc not working in any program (bug 1245473)

>  ----------------------
>
>  Can't set keyboard layout change to ctrl+shift, Caps Lock, alt+shift
>  etc. "Shift", "CapsLock" keys are just ignored in settings. Also the
>  default shortcut was set to "Super+Space" that is inconveniently,
>  because Dash is opening when you swich your keyboard layout.
