Above the cursor routing keys, are four rectangular shaped buttons. The
spacebar is located between these four rectangular shaped buttons.
Two of the rectangular shaped buttons are located on the left side of the
spacebar and the other two are located on the right of the spacebar.
These four rectangular shaped buttons are function keys. Moving from
left to right, the key that is the farthest to the left is called the F1 key, and
the key to the right of the F1 key is called the F2 key. Then, you will feel
the spacebar. The key that is to the right of the spacebar is called the F3
key, and the key that is to the right of the F3 key is the F4 key.
Above the function keys, you will find the Braille keys that are Perkins-
style, including the spacebar. If you have ever used a regular computer
keyboard, this setup is very similar to the keys on the home row on a
regular computer keyboard. When you are typing, you should place your
fingers on these 9 Perkins-style keys in the following manner:
Place your index finger, middle finger, ring finger, and pinky finger of
your left hand on the left four buttons. Then, place your 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, also
called the Space key.
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 that your left ring finger is on corresponds to dot
three. The button on which your left pinky finger is placed on is the
Backspace key.
The button that your right index finger is on corresponds with dot four in
Braille. The button that your right middle finger is on is dot five, and the
button your ring finger is placed on 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 where your thumbs are placed is called the
spacebar.
