The console gameplay is called Pause'n'Play. You have 6 hotkey slots set to X, Y, A (360) or [], ^, O (PS3). The first 3 you can do on the fly. The second 3 you have to press a button to flip to those to use. Any other skills you want to use but don't have on that, you'll have to go to the skills window which pauses the game. On PC you have a bar at the bottom of the screen that holds a good number of skills in it. And you just click em.
