Hey Karel, I used a medium sized sculptor's chisel and mallet to ... just kidding! My Stowaway still has the standard Qwerty layout on the keys themselves. I haven't tried to pry them up or modify the labels as they seem pretty well fixed to the spring mechanism. I'd imagine the easiest way to change the labels would be to try print or buy some on clear "see-through" adhesive / acetate. Though I guess you'd have to scratch away the labels on the keys you'd like to swap. Sorry I couldn't be of more help! ...graham.
