Question regarding FSDS 3.5

Hi guys first of all sorry if it was answered already but i've looked through threads and haven't found my answer.
Basically does anyone know how can i move my view. Like for example i'm working in in front view window and i'm kinda really zoomed (lets say to see vertices) and i just want to scroll up, is there a way?
