Transposition = adjacent pairs of letters are swapped
Omission = individual letters are missed out

QWERTY substitution = letters are replaced by each of their QWERTY-keyboard based physical neighbours (e.g. 'h' gets replaced with y, u, j, n, b, g)
QWERTY repetition type 1 = letters are followed by each of their QWERTY-keyboard neighbours
QWERTY repetition type 2 = letters are preceded by each of their QWERTY-keyboard neighbours
