Trackball mouseFollow

Hi,

I think im gonna get a mouse with a trackball, but I cant find this site that had the game manual in pdf.Anyone know what Im talking about, or can just tell me what teh options in the game with a mouse are since i usually use with my left hand, ( reason I ask is im at work and id go pick it up on lunchbreak)

i just want to know what the options are on the screen regarding the mouse movement etc.
thanks!!
