•To use picker hotkeys in animator mode:

MG-Picker Studio v2 reduces its hotkeys for animator mode further.

Most of the time, you are just using Maya hotkeys. In order to use the picker hotkey, you must make sure the picker window is currently active, and your mouse cursor is within the picker area.

So quick work-flow to use a picker hotkey in animator mode, is MMB activate a picker view, keep the mouse cursor within it, and then press the picker hotkey.
