Using controller / keyboard input to aim up in Unreal 4 Blueprint mode

Hello, I’m having issues trying to get a character in side-scroller mode to look up using keyboard/controller inputs. I’ve been trying for hours and whenever I search for how to do this, all I find are guides on shooting at a mouse location.

How I want this to function:
I press up on the controller, or push the left stick up, or press W on the keyboard, and my character will aim up, so that when I shoot a projectile, the projectile goes upwards.
