[VicPiMakers Projects] Jim's Challenge - Output 10 (caesar cipher)

[George Bowden]

Hi Michelle
If you are on a laptop or computer using chrome, you can hold down the CTRL
key and tap the letter u .  There are things further back than that but its
a start.  As for ink marks showing through, we try to avoid that because it
usually reveals security holes that the bad people exploit.
