Jake I only started using wasd lately, I use the cursor keys as they are much easier (for me) to understand. Sh- and Sh+ are not really pan, they are zoom, you can pan all around using a right mouse button. Alternatively you can use the F5 switch to go in and out of free cam mode and, while in it, then use the right mouse button to pan all over the place and the cursor keys to zoom in and out and pan left and rigt.
