They will also need to increase the minimum size of a non-chaff keystroke to be the size of the largest keystroke that they wish to keep confidential; 3 bytes is a minimum for the basic control characters (e.g. arrow keys which are ESC '[' X where X depends on the arrow direction).
I did find it interesting that the return keystroke was of a differing size to other characters; on unix systems it should just send a ^J.
