It could also be the "Cursor Mode" which you get by pressing the "." button I think. I have no idea what Cursor Mode is for, but that could be what it is too.
Maybe Cursor Mode is that Target Change that @MissBizz is referring to

Enjoy the game, life is what you really want to be worried about.

Thanks everyone for the help. Lynx is definitely right and I can think of a number of times when bad guys were too close together and I had a lot of difficulty getting the aim point to hit the right target. I use "." all the time to go to curser mode.
