Of course - there's no question that the shell shouldn't be completely
usable using just mouse input.

One question here is what constitutes 'more work'. The message that
began this thread phrased the issue in terms of how far the pointer has
to travel. That is certainly one valid metric, but there are others that
also need to be considered. If you look at application launching, the
shell requires less accuracy in the use of pointing devices than GNOME
2, for instance. In this light, you could probably count the shell as
requiring less 'work', particularly for people using low quality
trackpads or who have limited motor control.

The other question is whether we should be thinking just in terms of
efficiency. The shell's design has always had user experience as its
focus, and this is something which does not always neatly map onto
measures of efficiency.

(This is a largely academic debate, of course. We're two and a half
weeks off UI freeze.)

I know there are yet to be implemented plans for key navigation in the
shell, particularly in the overview, and I'm sure a lot of thought has
gone into them. Maybe a GOMS analysis could be useful there... I'm sure
you could talk to Jon or Jimmac about it on #gnome-design.
