Chapter 4: Programming

Double-high/Double-wide Keys
Several
keys
on
the
keyboard
can
accept
optional
keycaps
that
cover
two
keys
to
produce
double
‐
high
or
double
‐
wide
keys.
When
you
press
a
double
‐
high
or
double
‐
wide
keycap,
the
keyboard
firmware
sends
the
keycode
for
both
keys.
When
usages
are
the
same,
only
one
keycode
is
sent.
Using
the
programmable
key
matrix
feature,
the
keyboard
matrix
can
be
programmed
to
support
double
‐
high
or
double
‐
wide
keys
by
specifying
the
same
key
code
for
both
key
locations
supported
by
the
key
cap.
