keycode of interest
.TP
.I \- grp
group 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 XkbKeyGroupWidth
computes the width of the type associated with the group
.I grp
for the key corresponding to
.I keycode.
