SECTION 2 MASTERING THE NUMBER KEYS

U800002, Rev. 1.2, October, 2002

Why Learn Numbers Before Letters

Numbers are easier to learn. First, there are only ten numbers compared to 26 letters. Note

that the numbers are in order on your DataHand units just as they are on a flat keyboard.

Also, the letters of the alphabet are mixed on the DataHand just as they are on a flat

keyboard. Numbers are arranged in their numeric order and the letters are arranged in a

mixed fashion. So you have only 10 keys to learn in order, compared to 26 letters out of

order.

The use of numbers has increased dynamically. Think for a moment of how numbers affect

each one of us: Social Security Numbers, telephone numbers, credit card numbers, loan

numbers, zip codes, addresses, license numbers, and insurance policy numbers are only a

sampling of number use. In addition numbers are now used in context with letters so

frequently that the inability to key numbers at the same or higher rate than letters reduces

keyboard productivity significantly.

Number Trivia

The 0 (zero) is the most used number followed by the number 5 and then the number 1. Eight

is the least used number. The letter A is used with numbers more than any other letter of the

alphabet. Now that we have that information, let's get started.

Keys You Will Be Using

NAS (Numbers And Symbols) Mode - To activate the numbers, press down on the well key

with your right thumb until the system locks in the NAS mode. The indicator light will show

the NAS mode on your right hand unit.

Note that the left hand fingers are in the wells for keying the numbers 1 - pinky finger, 2 -

ring finger, 3 - middle finger, and 4 - index finger. To enter any of these numbers, press down

on the well key. The number 5 is entered by pressing with your left index finger east.

The right hand fingers activate the numbers 6 and 7 - index finger, 8-middle finger, 9 – ring

finger, 0 - pinky finger. The number 6 is entered by pressing the right index finger west, the

numbers 7, 8, 9, and 0 are entered by pressing down on the respective key.

Spacing between groups of numbers is done by pressing your right thumb east.

To move to the next line, press the Return key by pressing your left thumb west. The double

zero, comma, and decimal point keys will be introduced later.
