keycode of interest
.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 XkbKeyNumSyms
returns the total number of keysyms for the key corresponding to
.I keycode.
