That's a bit different. Court stenographers, along with the people who do real-time TV captions, use specialized chording keyboards (stenographs, they look like this [0]) that allow them to type words or even whole phrases with a single or just a few strokes. That's how they're fast - you can only go so far typing one letter at a time.

Right, I thought I had read you could actually enable some of the chording techniques on a standard keyboard at some time. Though, I don't recall the story. Quickly googling isn't showing too much.

Regardless, I know I could get faster than I am. I hover just over 80 to 90. To get a lot faster, I was always under the impression that I would need something like that. I have also always thought that I have no need for that. So it works out. :)

With n-key rollover, you can use Plover to mimic stenotype chording on typical qwerty. It's been posted/discussed here a few times, so that might be what you're thinking of.
