Mouse vs Keyboard (was: Re: editor wars (was Mac vs Unix...))

[bobr at zeus.UUCP]

There is no problem in using feet for simple controls (i.e., pressing a
pedal or three and having fairly fine pressure control over them), but we
are talking about a mouse replacement here.  Human feet (disregarding the
exceptional cases) do not have the sensitivity to control a device which
could replace the sensitivity and degrees of freedom of a mouse.
