1337 Spe4k is a very complex topic.
I've covered some basic small parts of it.
Now you can enter your matrix for 1337 speak but only for A-Z.
I have to figure out how to add the rest
I saw new BatMan trailer and on the end of trailer there was ?0?1
so ? (question mark) is probably a replacement for number 2.
I'll try to add this feature ASAP.
