Keyboarding vs the mouse

We’ve done a cool $50 million of R & D on the Apple Human Interface. We discovered, among other things, two pertinent facts:

• Test subjects consistently report that keyboarding is faster than mousing.
• The stopwatch consistently proves mousing is faster than keyboarding.

This contradiction between user-experience and reality apparently forms the basis for many user/developers’ belief that the keyboard is faster.

I believe in something demonstrably false.

Tog, in pointing out the use of command-x, -c, and -v, concludes "two-handed input can result in solid productivity gains (Buxton 1986)." I believe that.
