Check out _Tog_on_Interface_ by Bruce Tognazzini, Addison-Wesley
Publishing Company, 1992. If I remember correctly, his findings
indicate the mouse is *actually* faster than keyboard shortcuts, but
that many of the test subjects *perceived* the keyboard shortcuts to
be faster.

That said... Have you considered structuring your materials to
address both types of access? Or doing some usability testing on your
specific application to see which methods your target users prefer?

You might find, for example, that the mouse works better for some
purposes, the keyboard shortcuts for others. You can then tailor your
docs accordingly.
