mable chords. And, since most of these key combina-
tions are not preset at the factory, you can customize
your Twiddler2 by making your own assignments to
these chords. You can even override factory-preset
key/chord/character assignments. Custom chording is
explained in the section on

TYPINGON THE TWIDDLER2
Single Keys
There are twelve keys on the front of the
Twiddler2 arranged in three columns and four rows.
Each key in the center column has a tiny bump which
makes touch-typing easier by letting you know immedi-
ately, by touch, which key your finger is pressing.
Each of your fingers is assigned to a specific
row of three keys across. Your index finger presses the
keys marked
A
,
E
, and
SP
(space) in the first or top
row. Use your middle finger to press
B
,
F
, and
DEL
(delete) in the second row. Your third (ring) finger is for
the
C
,
G
, and
BS
(backspace) keys in the third row.
And your little finger (pinkie) is in position for the keys in
the fourth or bottom row--
D
,
H
, and
ENT
(enter). Press
and release any of these keys singly to type the charac-
ter or command with which the top of the key is labeled.

umn, you will find that the left and right columns of keys
are an equally short reach for your fingers. If the strap
is too tight, the closest column may cramp your
fingers. If the strap is too loose, the column farther
away may be hard to reach.
You can comfortably rest your thumb on the inside
corner of the Twiddler2, in a relaxed position, as
shown in the photograph on the back cover
.
You don't need to grip the Twiddler2. By resting the
thumb as shown, and applying gentle
outward
pres-
sure, you will keep the Twiddler2 steady and reach the
keys more easily.
THE KEYBOARD
The Twiddler2 keyboard is designed to do all
the work of a standard computer keyboard plus a lot
more. With only sixteen keys, the Twiddler2 accom-
plishes this by
chording
.
On a piano keyboard you can play a single note
by striking one key or play a chord by playing a number
of keys at the same time. The Twiddler2 works in a sim-
ilar way. You can type a character or command with a
single key or with a combination of keys called a
chord
.
Using various single keystrokes or chords, you can type
all the letters, characters, symbols and commands
found on a standard keyboard. In fact, the Twiddler2
actually offers you over a thousand different program-
