-// This macro is an example of using a non-standard row-column matrix. The
-// keyboard in question had 11 rows and 8 columns, but the rows were not all
-// horizontal, and the columns were not all vertical. For example, row 2
-// contained "Print Screen", "N", "M", ",", ".", "/", "Right Shift", and
-// "Left Alt". Column 0 contained "F6", "7", "O", "'", "Q", "D", "B",
-// "Left Alt", "Up Arrow", and "Down Arrow".
-//
-// The macro makes programming the keys easier and in a more straight-forward
-// manner because it realigns the keys into a 6x15 sensible keyboard layout
-// instead of the obtuse 11x8 matrix.
