-// Keyboard layout is a 2D array of scan codes.
-//
-// First dimension is the Key ID of a given key. Key IDs are the indices of the
-// of the active keys of the key_matrix_t structure. In case of left half, an
-// offset of 35 is added.
-//
-// For each Key ID, there are 4 different possible scan codes:
-//      - default, when no modifiers are pressed
-//      - mod layer
-//      - fn layer
-//      - mod+fn layer
