The key width and number of groups associated with a key are used to form a  small two-dimensional array of KeySyms for a key. This array may be different  sizes for different keys. The array for a single key is stored as a linear list,  in row-major order. The arrays for all of the keys are stored in the syms field of the client map. There is one row for each group associated with a key  and one column for each level. The index corresponding to a given group and  shift level is computed as:

     idx = group_index * key_width + shift_level

The offset field of the key_sym_map entry for a key is used to access the beginning of the array.

XkbKeySymsOffset returns the offset of the two-dimensional array of keysyms for the key  corresponding to keycode.
