On each side of the Braille display are two capsule shaped keys. These are
the "UP" and "DOWN" scroll keys. The scroll keys are used to scroll the
Braille display through menus, fields, lists or text. You can use the scroll
keys to scroll by display length or line.
Above the Braille display are the Perkins keyboard and the function and
navigation keys. Near the center of the unit is a 9 key Perkins-style
keyboard, consisting of Braille dots 1:6, "SPACE", "BACKSPACE", and
"ENTER". When you are typing, you should place your fingers on these 9
keys in the following manner:
Place the index finger, middle finger, ring finger, and pinky finger of your left
hand on the left four buttons. Then, place the index finger, middle finger,
ring finger, and pinky finger of your right hand on the right four buttons.
Finally, place both of your thumbs on the spacebar.
The button where you placed your left index finger corresponds with dot
one in Braille. The button that your left middle finger is on corresponds to
dot two, and the button under your left ring finger corresponds to dot three.
The button on which your left pinky finger is placed is the Backspace key.
The button under your right index finger corresponds with dot four in Braille.
The button under your right middle finger is dot five, and the button on
which your ring finger is placed corresponds with dot six in Braille. The
button on which your right pinky is placed is the Enter key. And, the long
bar shaped button under your thumbs is the spacebar.
On the same row as the Space bar are 8 rectangular function keys: four to
the left of the spacebar, and four to the right. Moving from left to right, these
keys are numbered f1-f8 and are programmed with the following functions:
Esc, Tab, Ctrl, Alt, Shift, Insert, Windows, and Applications.
On each of the upper left and right corners of the top face of the Braille
EDGE 40 are 4 buttons in a circular pattern. These are the navigation
buttons and correspond to UP, DOWN, LEFT, and RIGHT arrows
