If you don\'t want to use the mouse to turn and aim, then I am pretty sure you can add keyboard maps for it in one of the .cfg files.
further inspection showed me that there is a nice complicated keymap.cfg file in the data directory with in the cube directory, and I had no idea how to make the mouse do it. In linux you could use access controls to make the aarow keys move the mouse though, so perhaps windows has an equivilant.
