How to move the camera?

I want to move my camera amongst the drawing stage. Just to whatever side–left right, up down. To move to another drawing someplace else, or making a shake or “earthquake” camera effect thinggy…
I’ve looked up tutorials and they’re mostly focused on doing parallax scenes, or just seem too complicated to understand… I just simply wanna move the lil rectangle, and the lil rectangle ONLY… around the drawing space. Could someone help me out and explain it to me straight? It’d be a huge help. Thanks.

I am short on time but here are a few sources. By the time you have watched any that you didn’t earlier you may be in a position to figure it out.
