Camera Controls

One of the things you will want to do in Second Life is to control your view of the world. Camera Controls allow you to do that. go under the View menu at the top of your screen and choose the item, Camera Controls.
A control panel similar to this one appears. Each of the three blue items has a specific function. The blue circle on the far right rotates the camera around your avatar so you can see all around. The middle bar with a plus and minus moves the camera closer or farther from the object. The third object, the blue circle on the right is for moving the camera up and down and left and right. Just click on one of the four points of the arrows to choose your direction.

There are other ways to move the camera as well and here is a short video explaining some of the other controls.

Here is another video about camera controls, this one is a little more advanced.
