I disagree with their decision to not show the keyboard on the screen, because from my experience (never learning touch-typing until I switched to Dvorak) it is vital to not look at the actual keyboard to know where the characters are, but on the small netbook-style laptops at Shishur Sevay it is better to print the keyboard layout and mount it next to the monitor.
