Check out this keyboard mod that Charlie Webb from NortHACKton came up with. You can never have too much automation, I love the big red button which allows a predetermined string of text to be sent to the computer when pressed. There are some additional pictures and schematics here.
“NortHACKton member, Charlie Webb, recently completed this project based around an arduino and a keyboard. Fed up with the way Windows forced him to switch between his different keyboard layouts (qwerty to Dvorak) he decided to take the process entirely out of windows hands.”
