You can also right mouse click on an entity, which zooms in on it. Once zoomed in you can then zoom in and out with the mouse wheel and use one of the mouse buttons to drag around the view. You can also use some keys to move the entity's position. I can't remember the exact keys, but the status bar might tell you this. I think it's PgUp/PgDn and arrow keys, but not sure.
