I fully agree with your second point and your first point also is a
very good one and I didn't think of it that way. But I'm not quite
convinced that for a touch typist, looking at the keyboard is more
convenient than navigating with the mouse. Memorizing the shortcut
key combinations specially those most in use, seems to me to be the
ultimate choice of users. This may look as 'power user' behavior but
it is not. As 'touch typing' was the behavior of professional typists
but it is increasingly becoming the common practice.
