The digits and several symbols stay in the same place, but other than A and M, all letters change places. The vowels A, O, E, U, I (in that order) are assigned to the home row for the left hand.
Although this keyboard was designed to be more efficient than the QWERTY keyboard, the results are apparently controversial (see the Brooks link).

Examples

			First row is P, Y, F, ... which are respectively the 16th, 25th, 6th, ... letters; second row is A, O, E, U, I, ... which are respectively the first, 15th, 5th, 21st, 9th, ... letters; third row is Q, J, K, ... which are the 17th, 10th, 11th, ... letters.
