There are keyboard bindings available that mimic a gamepad's targeting, and I'd imagine the filter settings apply to those keys. I believe it's numpad 4 and 6 by default. Note that these keys soft-target something (giving you the circle on the 3D model and allowing you to cast spells etc. on it, without making it your target), so to switch targets to something you select with these keys, you also need a confirm key bound (numpad 0 by default).

(All of this is gleaned from other threads I have a relatively certain memory of; no warranty supplied.)
