Keyboard shortcut for run/show/cycle [or hide] in KDE 5

I'm testing out KDE 5 from ktown, really quite nice so far, I'm impressed. In awesomewm though I had keybindings for specific programs that would (a) run the program if it wasn't loaded, (b) switch to that window if it is already running but not focussed, or if it already has focus (c) cycle through other windows of the same application (if there are any). Actually for some programs I want (c) to be "hide the window if it has focus" instead of cycling.

Anyone have a nice solution for that kind of thing in KDE? I could probably do it with xbindkeys and some scripting stuff, but am wondering if there's an easier way.
