You can use the arrow keys to move the view that your mouse is on, or press space and then click.
One useful shortcut that I use all the time is ctrl+e, which centers all the 2D-views on the object that you have selected, also if you press ctrl+shift+e it centers the 3D-view on the object you have selected.
Shift is already being used to quickly copy+paste objects. You can make a whole row of copy-pasting by selecting a thing and then holding shift + any arrow key.
