- I hate posting this in general, but here goes.
-
- Yes, it is an urban legend. The QWERTY keyboard was designed to
- minimize jamming by placing common key sequence far apart. This is
- a mechanical distance, not physical distance on the keyboard itself.
- If you look at the 'e' 's' and 'd' keys, you will see that 'e' is on
- the row above 's' and 'd', so they are mechanically far apart.
-
- About 15 or 20 years ago there were a number of studies done on
- keyboard layout (you can look at old issues of Human Factors and
- Ergonomics to find them). The net result of these studies is that
- keyboard layout doesn't matter that much, 5-10% difference in typing
- speed at the very most. If you really want to type fast look at
- a chording keyboard, or change the shape of the keyboard itself.
