Both first and third person point-of-view (POV) are available. Click the Actions button on the menu to open the Action Menu. Select the Camera sub-menu to get access to the different camera modes.
In third person POV, move the camera around by holding the CTRL button and the right mouse button while moving the mouse around, or use the NumPad arrow keys. Pressing 5 on the NumPad puts the camera back in its default position for the selected mode.
Pressing F10 opens the Options Menu. Go to the Keyboard menu to look at the different keyboard options.
The options menu contains a lot of information and preferences that you should gradually get familiar with.
