It seems like <,:, and certain other characters don't work. Also, why do you skip over white-space?

It is interesting. I wonder if I can learn to make fewer typos.

I had issues with the '-' character (for example, in the first line of the Shell Git lesson), and I'm just using the standard US keyboard layout.

EDIT: also '_', as sp332 commented. Firefox on OS X.

Me too with '-', also with Firefox (Nightly) on OS X (10.6.8). However, it seems to work fine with Safari.

I also had problems with the fist line in the rails example: require 'active_support/core_ext/object/blank'

I have a swiss german keyboard and I can't get past the first _'_ character. I'm using XP and Firefox. Otherwise a really neat idea.

It seems to me that any character that needs to be typed using alt gr can't be detected (using Firefox as my browser and BÉPO as my keyboard layout).
