+.SH DESCRIPTION
+.LP
+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
+.I 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:
+.nf
+
+ idx = group_index * key_width + shift_level
+
+.fi
+The
+.I offset
+field of the
+.I key_sym_map
+entry for a key is used to access the beginning of the array.
+
+.I XkbKeyGroupsWidth
+computes the maximum width associated with the key corresponding to
+.I keycode.
