Indeed, and the implication that away and out is the natural
direction.  Swinging my arm inward and pulling it toward me seems to
put stress on tendons in the shoulder; when the arm is closer, it
pushes against the torso; an inward wrist movement seems more
stressful than an outward one; extending the fingers pushes the mouse
away (and lowers the hand, straightening the wrist), curling them to
pull is more awkward but also common (and tilts the hand upward,
creating a sharp angle at the wrist and increasing stress throughout
the motion).

Though the fact that the fastest and most natural movement when
initially grabbing for the mouse seems to be out and away does seem
