EYBOARD
The keyboard is a KeyTronics™ device. It is similar to a standard typewriter keyboard
except that it has several additional keys. You use some, though not all, of the additional
keys with PowerScript.
We won't discuss any of the individual keys here—you'll learn about them in other chap-
ter of this manual. Some of the key groups deserve special attention.
Esc
(Escape)
Enter Keys
The keyboard has two keys labeled "Enter." One is on the keypad, the other on the Key-
board Keys. When referring to the latter (on the Keyboard Keys), this instruction manual
identifies it as the Alpha Enter key. The keypad Enter key is referred to as the Numeric
Enter key.
Function Keys
The function keys are labeled F1 through F12. They are called function keys because they
can be used (under program control) to perform specific functions. The precise function
that any given key performs is controlled programmatically. PowerScript makes extensive
use of the function keys.
Mode Keys
There are nine mode keys, in two separate groups. You use some of the mode keys for
controlling the playback of projects.
There are three lights on the LED panel. They glow when the associated key has been
LED's
depressed and is active. That is, when you press the Num Lock key to activate the feature,
the Num Lock LED glows. Likewise, pressing the Caps Lock and Scroll Lock keys cause
their LED's to glow. Pressing a key again deactivates the feature and the LED turns off.
