I guess I should've said, move the sensor's position by pressing the left/right/top/bottom buttons around the Menu/OK button. The best I have been able to determine is that you first have to hit the down button and then you can move it around. Seems like somewhat of a basic capability of a camera to give the ability to move the sensor that the camera uses to focus on. For example, if the camera is currently using the upper left location, I just want to tap the right button to move it over to the right without tapping any additional buttons.
