Keyboard
The keyboard consist of two sections. The lower section contains 63 keys
laid out in a QWERTY-type typewriter keyboard arrangement. The upper
section consist of 14 touch control keys. The 10 function keys are user
defined by software. The 4 icon keys initiate functions unique to this com-
puter. An illustration of the keyboard, with the keys being explained out-
lined in black, accompanies each discussion.
All keys except the SHIFT, CTRL, ALT, CAPS LOCK, and NUM LOCK
keys generate repeat entries. When the key is held down, the letter (or
other symbol) will start repeating. The longer the key is held down, the
faster the repeat entry is generated. .
