During team meetings, "driving a mouse" would slow the flow of a presentation. I became the default computer operator for these meetings because I knew all the "shortcut keystrokes" for navigating a disk, a document, and presentation. Interestingly, if you call a keystroke an "accessibility" feature, most folks will ignore it. If you call a keystroke a "shortcut," some folks will catch on (and nerds will devour it).
Um, thanks. I needed that. ;-)
