I developed a little application several years ago that allows the receptionists to track all our correspondence in a database. It ties the scanned image to the data entered in the database.
One of the users recently asked me to make some changes to the forms I had set up for data entry. Our conversation went like this:
User: I'd really like to avoid having to switch back and forth between the keyboard and the mouse when finishing one record and creating the next record.
Me: Good idea; I can do that. *Clicky. Clickyclick. Tappitytaptap.* There, done! Now all you have to do is hit Tab twice to get to the new record.
User: Thanks, but I don't wanna do that. I'll have to look down at my keyboard to make sure I hit the Tab key, and that takes as long as just using the mouse.
Me: No, it doesn't. You use the Tab key all the time. Just tap it twice, and you're good to go. If you still don't want to do that, then you'll have to use the mouse.
User: Well, it's such a bother. I don't like either option.
Me: So...you're saying you don't want to use the keyboard or the mouse?
User: Yeah, I guess so.
Me: Then I'll need to work another method of input. Let's see...how about telekinesis? No? A joystick? No? How about just doing your job, is that an option?
