What is target filtering/cycling?

[JohnJSal]

I hope im actually understanding u correctly (its late here) but what im saying is ppl ADD to the basic settings..like in my example so they can also tab/triggertarget to players when in battle. So jt isnt a filtering OUT ,its a filtering IN.

The filters in my settings have everything checked, yet it still doesn't target anything but enemies. I suppose it could only apply to a controller, but there are even more settings underneath these settings that are grayed out and have specific controller options, like the buttons on a controller. The settings that are available to me seem to apply to a keyboard setup, yet don't seem to work. Maybe it's more controller stuff.
