keyboard sniffing video question

[dninja at gmail.com (Robin Wood)]

I've just watched a couple of videos on the keyboard sniffing and
looking at the software it was wondering how it knew when to start
decoding. The screen showed a list of collecting key messages then
decoding messages. The first video was 8 characters (password) the
second 12. It could have been hardcoded for the demo but it seems a
little odd.

I'd like to believe it is true but this just makes me question it a little bit.
