Sorry, just RTFM again but C Fn 2 does not seem very useful:
2:
While exposrue metering is active, turn the main dial to select a hor AF pt (if C Fn 13-3 has been set, select a peripheral AF pt). This is also possible during continuous shooting in the AI Servo AF mode or while you are pressing the shutter button halfway. The AF pt selection stops at the extreme left, extreme right, top-most and bottom-most AF pts.
During autofocusing, yoou can press the AF pt button to switch instantly to the automatic AF pt selection mode.
Yoou can also select the AF pt (including auto AF pt selection) by same operations of C.Fn-11-1.
If both C.Fn-11-2 and C.Fn-18/1/2 have been set, select a vertical AF pt by pressing the <+/-> button and turning the main command dial.
Not sure why you think C.Fn-11-2 is nice, really wanna know.
