Dvorak.

I was always curious: What is a Dvorak keyboard? The usual suspect 
when a Linux login fails.

A quick search on Satan's archive (Google) learns the history of 
typewriters. The mapping of the keys and the joke of the word 
typewriter on the top row is not efficient. The hammers don't jam 
anymore. 

so I ordered some qwerty/Dvorak stickers to mess up my
keyboard. And I must admit, you pick it up easily.
I want to give it a try for reduce RSI and speed up my 
typing speed up from 6 fingers QWERTY to 10 fingers 
Dvorak.
