"It takes two seconds to decide upon which special-function key to press. Deciding among abstract symbols is a high-level cognitive function. Not only is this decision not boring, the user actually experiences amnesia! Real amnesia! The time-slice spent making the decision simply ceases to exist. While the keyboard users in this case feels as though they have gained two seconds over the mouse users, the opposite is really the case. Because while the keyboard users have been engaged in a process so fascinating that they have experienced amnesia, the mouse users have been so disengaged that they have been able to continue thinking about the task they are trying to accomplish. They have not had to set their task aside to think about or remember abstract symbols. Hence, users achieve a significant productivity increase with the mouse in spite of their subjective experience." this is not research, this is jingoism. i've heard this study cited so many times but never read it ... i'm astonished it is so bad. 2 seconds to decide what command key sequence to press? Sure, if you contort your test so much (only novel command sequences) that the results apply only to your contrived situation.
