Blueprint Question

I’m working on my Student Innovation Project for my degree, and I’ve run into a wall. I’m working on a simple system mechanic where the player can move the camera up and down, select a given component, and change values. The problem I’m facing is that I haven’t the foggiest what to begin researching for using the camera in lui of a pawn, and how to set up movement as only along the Z axis. Anyone got some helpful suggestions on what to research to get this snag taken care of please?

I apologize if this is in the wrong spot, but it was the only place that looked like a good one to post into.
