              keycode of interest

       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.
