Arrow key problem

I used to use another program sort of like this one. When I made animations or sprites I usually needed the arrow keys to move the sprites so they could be in a perfect position since using the mouse isn’t too steady. Still, here it just doesn’t work it moves too much and there isn’t a specific way of changing how many pixels it moves. I can just use my mouse I know but sometimes I need to move an object in a certain direction I can’t hold down shift to move it either and using the arrow keys won’t work because it moves too far is there any way I could find a mini solution for this? It’s not THAT big of a deal but I would like it if there was one.
