Originally posted by RBellavance It's the same as when you're not in LiveView, i.e. press "Ok" before the 4-way pad. You must be in "SEL" mode, of course.
There is also a custom option that reverses the function of the "Ok" button, i.e. the 4-way pad defaults to moving the AF point, and you must press "Ok" first to access the function of each button.
I found it by trial and error! Strange for me it works in all AF modes. Very useful for macro work. Thanks for the response.
Also you can use the info button almost the same way though not as accurate.
