I'm a quicksave addict. I tried playing with a xbox controller, but I have to press five buttons? just to save. I also open the map every 2 seconds...
Is there a way to use the controller AND the keyboard?
Of course not, why would anyone on PC want to use their keyboard to game? Especially after you plug in a gamepad? Honestly, some people....
Jokes aside, no, you can't. In fact, the friend of my son's who I mentioned a loooooong way up the thread (who played on PC using her controller) has noted, loudly, on several occasions (cough) that she had to uninstall the game completely and reinstall in order to get the keyboard to work at all with the game again.
I refrained from saying that it was her own fault for giving in to the collective. So proud of myself. 
Others on the thread have also noted some difficulty re-initialising the KB&M even after unplugging the controller. In any case, once the gamepad's in there, it takes over, completely. There is no simultaneous KB&M and controller use.
