On Rails Camera Control using Animations

Hi all,

I'm new to Unity and I have the following question: I'm trying to guide a camera through a grid and I have an animation set for the camera to move to the first intersection but afterwards I want to be able to choose whether to go left or right through a button press, repeating the process for every intersection. However because I am so new to Unity this is pretty foreign to me, would anyone be willing to help me? Any advice would be greatly appreciated.
