Cali is talking about STI shifting. It's Shimano's integrated braking/shifting mechanisim.
I think most new production bikes have STI or it's Campy equivalent. Maybe Pedalfaster or Emily in NC can chime in here.
It sounds like Calla has been riding with friction down tube shifters. Look for the levers on the down tube in the following picture.

Then there are bar end friction shifters. That's what I use on my road bike. They are the silver levers on the ends of my bars. http://www.tandemhearts.com/bike/ram...-w-fenders.jpg
I know when I first got my bike I probably looked down to shift.
I don't anymore. It becomes just a natural motion. When Iwas captaining our tandem with STI it was kind of weird at first because I would reach for the bar end to shift. I rode the bike a lot without a stoker to get use to the different shifting.
