A form of typing in which certain letters are replaced by numbers or other symbols that look relatively similar to the original letter, such as using '3' instead of an 'E' or '1' instead of 'I' or 'L'. Typing Quirks are commonly seen as beneficial to people with Dyslexia, as the symbol-replacements catch the reader's attention. They are also commonly used among emo culture, and Homestuck fans.
