Unity-style window activation in KDE

I have used unity in Ubuntu for a long time and i’m very used to use Win+[number] key combination to switch to windows. For example i have Win+1 to switch to terminal emulator. Some months ago I have tried new KDE5 and it was awesome. But I found no way to activate (or launch if not started) application on shortcut :) Only lunch a new one every time, but it’s not what i want.
